Haptoglobin is a plasma protein of mammals that plays a crucial role in vascular homeostasis by binding free haemoglobin released from ruptured red blood cells. Trypanosoma brucei can exploit this by internalising haptoglobin-haemoglobin complex to acquire host haem. Here, we investigated the impact of haptoglobin deficiency (Hp-/-) on T. brucei brucei infection and the parasite´s capacity to internalise haemoglobin in a Hp-/- mouse model. The infected Hp-/- mice exhibited normal disease progression, with minimal weight loss and no apparent organ pathology, similarly to control mice. While the proteomic profile of mouse sera significantly changed in response to T. b. brucei, no differences in the infection response markers of blood plasma between Hp-/- and control Black mice were observed. Similarly, very few quantitative differences were observed between the proteomes of parasites harvested from Hp-/- and Black mice, including both endogenous proteins and internalised host proteins. While haptoglobin was indeed absent from parasites isolated from Hp-/-mice, haemoglobin peptides were unexpectedly detected in parasites from both Hp-/- and Black mice. Combined, the data support the dispensability of haptoglobin for haemoglobin internalisation by T. b. brucei during infection in mice. Since the trypanosomes knock-outs for their haptoglobin-haemoglobin receptor (HpHbR) internalised significantly less haemoglobin from Hp-/- mice compared to those isolated from Black mice, it suggests that T. b. brucei employs also an HpHbR-independent haptoglobin-mediated mode for haemoglobin internalisation. Our study reveals a so-far hidden flexibility of haemoglobin acquisition by T. b. brucei and offers novel insights into alternative haemoglobin uptake pathways.

(1) Background: This study evaluated the effects of a plant bioactive (Phyto Ax’Cell, Phytosynthese, Mozac, France) on the inflammatory status and health of dairy cows during calving. (2) Methods: 46 Holstein crossbred cows were randomized into a control group (CON, n = 23) and the Phyto Ax’Cell group (PAC, n = 23). PAC received Phyto Ax’Cell at 25 g/cow/day, from 15 days prepartum to 7 days postpartum. Blood analyses were performed weekly from D-7 to D14 to evaluate the energy metabolism and inflammatory status; rectal temperature was measured daily within 14 days from calving day (D0). (3) Results: PAC showed lower serum haptoglobin at D7 (0.55 vs. 0.79 mg/mL; p < 0.05) and D14 (0.44 vs. 0.66 mg/mL; p < 0.05). CON had a higher number of circulating white blood cells and granulocytes on D7 (p < 0.05). Fewer cows from PAC showed hyperthermia (≥39 °C) during the first 2 weeks postpartum (−7%, p < 0.05). Energy metabolism, which was represented by the NEFA/cholesterol ratio, improved (0.21 vs. 0.36 at D0, p < 0.1; 0.19 and 0.15 vs. 0.36 and 0.32, respectively, at D+7 and D+14, p < 0.05) under the plant bioactive supplementation. (4) Conclusions: The results suggest that the anti-inflammatory plant bioactive compound with Brazilian green propolis administered during calving had a beneficial effect on the energy and inflammatory status of dairy cows.

Methods of structural mass spectrometry have become more popular to study protein structure and dynamics. Among them, fast photochemical oxidation of proteins (FPOP) has several advantages such as irreversibility of modifications and more facile determination of the site of modification with single residue resolution. In the present study, FPOP analysis was applied to study the hemoglobin (Hb) - haptoglobin (Hp) complex allowing identification of respective regions altered upon the complex formation. FPOP footprinting using a timsTOF Pro mass spectrometer revealed structural information for 84 and 76 residues in Hp and Hb, respectively, including statistically significant differences in the modification extent below 0.3%. The most affected residues upon complex formation were Met76 and Tyr140 in Hbα, and Tyr280 and Trp284 in Hpβ. The data allowed determination of amino acids directly involved in Hb - Hp interactions and those located outside of the interaction interface yet affected by the complex formation. Also, previously modeled interaction between Hb βTrp37 and Hp βPhe292 was not confirmed by our data. Data are available via ProteomeXchange with identifier PXD021621.

Covalent labeling of proteins in combination with mass spectrometry has been established as a complementary technique to classical structural methods, such as X-ray, NMR, or cryogenic electron microscopy (Cryo-EM), used for protein structure determination. Although the current covalent labeling techniques enable the protein solvent accessible areas with sufficient spatial resolution to be monitored, there is still high demand for alternative, less complicated, and inexpensive approaches. Here, we introduce a new covalent labeling method based on fast fluoroalkylation of proteins (FFAP). FFAP uses fluoroalkyl radicals formed by reductive decomposition of Togni reagents with ascorbic acid to label proteins on a time scale of seconds. The feasibility of FFAP to effectively label proteins was demonstrated by monitoring the differential amino acids modification of native horse heart apomyoglobin/holomyoglobin and the human haptoglobin-hemoglobin complex. The obtained data confirmed the Togni reagent-mediated FFAP is an advantageous alternative method for covalent labeling in applications such as protein footprinting and epitope mapping of proteins (and their complexes) in general. Data are accessible via the ProteomeXchange server with the data set identifier PXD027310.

BACKGROUND: Unconjugated hyperbilirubinemia, a feature of neonatal jaundice or Crigler-Najjar syndrome, can lead to neurotoxicity and even death. We previously demonstrated that unconjugated bilirubin (UCB) can be eliminated via transintestinal excretion in Gunn rats, a model of unconjugated hyperbilirubinemia, and that this is stimulated by enhancing fecal fatty acid excretion. Since transintestinal excretion also occurs for cholesterol (TICE), we hypothesized that increasing fecal cholesterol excretion and/or TICE could also enhance fecal UCB disposal and subsequently lower plasma UCB concentrations. METHODS: To determine whether increasing fecal cholesterol excretion could ameliorate unconjugated hyperbilirubinemia, we treated hyperbilirubinemic Gunn rats with ezetimibe (EZE), an intestinal cholesterol absorption inhibitor, and/or a liver X receptor (LXR) and farnesoid X receptor (FXR) agonist (T0901317 (T09) and obeticholic acid (OCA), respectively), known to stimulate TICE. RESULTS: We found that EZE treatment alone or in combination with T09 or OCA increased fecal cholesterol disposal but did not lower plasma UCB levels. CONCLUSIONS: These findings do not support a link between the regulation of transintestinal excretion of cholesterol and bilirubin. Furthermore, induction of fecal cholesterol excretion is not a potential therapy for unconjugated hyperbilirubinemia. IMPACT: Increasing fecal cholesterol excretion is not effective to treat unconjugated hyperbilirubinemia. This is the first time a potential relation between transintestinal excretion of cholesterol and unconjugated bilirubin is investigated. Transintestinal excretion of cholesterol and unconjugated bilirubin do not seem to be quantitatively linked. Unlike intestinal fatty acids, cholesterol cannot "capture" unconjugated bilirubin to increase its excretion. These results add to our understanding of ways to improve and factors regulating unconjugated bilirubin disposal in hyperbilirubinemic conditions.

The aim of our study was to assess the presence and degree of intestinal leakage in subjects suffering from short bowel syndrome (SBS) and its modification by parenteral nutrition. To this end we assessed circulating levels of selected makers of intestinal permeability including zonulin, fatty acid binding protein 2 (FABP-2), citrulline and glucagon-like peptide 2 (GLP-2). We also measured lipopolysaccharide binding protein (LBP) as a marker of circulating levels of lipopolysaccharide acting through the CD14 molecule. Eleven SBS and 10 age- and BMI-matched control subjects were included into the study. The effect of parenteral nutrition was assessed after 14 days, 6 and 12 months from its initiation, respectively. At baseline, SBS patients had increased gut permeability as measured by zonulin (47.24+/-2.14 vs. 39.48+/-1.20 ng/ml, p=0.006) and LBP (30.32+/-13.25 vs. 9.77+/-0.71 microg/ml, p<0.001) compared to healthy controls. Furthermore, SBS subjects had reduced FABP-2, unchanged citrulline and increased sCD14 and GLP-2 relative to control group. Throughout the whole study period the administered parenteral nutrition had no significant effect on any of the studied parameters. Taken together, our data show that patients with short bowel syndrome have increased intestinal permeability that is not affected by parenteral nutrition.

BACKGROUND: Recent studies show that the haptoglobin phenotype in individuals with diabetes mellitus is an important factor for predicting the risk of myocardial infarction, cardiovascular death, and stroke. Current methods for haptoglobin phenotyping include PCR and gel electrophoresis. A need exists for a reliable method for high-throughput clinical applications. Mass spectrometry (MS) can in principle provide fast phenotyping because haptoglobin α 1 and α 2, which define the phenotype, have different molecular masses. Because of the complexity of the serum matrix, an efficient and fast enrichment technique is necessary for an MS-based assay. METHODS: MALDI plates were functionalized by ambient ion landing of electrosprayed antihaptoglobin antibody. The array was deposited on standard indium tin oxide slides. Fast immunoaffinity enrichment was performed in situ on the plate, which was further analyzed by MALDI-TOF MS. The haptoglobin phenotype was determined from the spectra by embedded software script. RESULTS: The MALDI mass spectra showed ion signals of haptoglobin α subunits at m/z 9192 and at m/z 15 945. A cohort of 116 sera was analyzed and the reliability of the method was confirmed by analyzing the identical samples by Western blot. One hundred percent overlap of results between the direct immunoaffinity desorption/ionization MS and Western Blot analysis was found. CONCLUSIONS: MALDI plates modified by antihaptoglobin antibody using ambient ion landing achieve low nonspecific interactions and efficient MALDI ionization and are usable for quick haptoglobin phenotyping.

AIM: To assess vitamin D status and health correlates in a sample of apparently healthy Caucasian participants residing in an urban area, Athens, with latitude 370 58' 0" N and longitude 230 43' 0" E, after taking into consideration a broad range of purported biological, behavioural and environmental factors. METHOD: Men and women 35+ years from a selected population (n = 490) were studied. Participants completed a detailed questionnaire regarding socio-demographic, lifestyle, clinical and dietary characteristics. Biomarkers were measured after 12 h fasting. Linear and multinomial regression models were used to evaluate the association between 25(OH)D and determinants of vitamin D status. RESULTS: Results revealed that one hour increase of sunlight exposure decreased the odds of having D deficiency (i.e., < 20 ng/mL) by 70% (OR = 0.30, 95% Cl: 0.20-0.45), adjusted for age, sex, family status, physical activity, smoking habits, BMI, triglycerides, parathyroid hormone, uric acid, haptoglobin, folate acid and haemoglobin, as compared to sufficient levels (i.e., >30 ng/mL). Regarding biomarkers, parathyroid hormone and haptoglobin were found to be related with the odds of having vitamin D deficiency (OR = 1.11, 95% CI: 1.05-1.16; OR = 1.02, 95% CI: 1.00-1.03, respectively) as compared to the sufficient levels. CONCLUSIONS: Sufficient serum vitamin D levels were observed among participants with characteristics associated with reduced cardiovascular risk, such as normal BMI, increased physical activity, decreased parathyroid hormone and decreased inflammatory markers. Even a slight increase in sunlight exposure could have beneficial effects on serum vitamin D concentrations and eventually on haemoglobin and inflammatory markers levels, thus providing a simple and inexpensive lifestyle intervention that promotes public health.

BACKGROUND: The scavenger receptor for complexes hemoglobin-haptoglobin (CD163), which is expressed on monocytes/ macrophages, is shed to the body fluids in a soluble form (sCD163). OBJECTIVES: To evaluate the dynamics of sCD163 in the blood of patients undergoing cardiac surgery. PATIENTS AND METHODS: Sixty-one adult patients who underwent coronary artery bypass grafting (CABG) were enrolled in the study. They were assigned to undergo CABG using either cardiopulmonary bypass (CPB), "on-pump", (22 patients), modified CPB, mini "on-pump", (17 patients) or without CPB, "off-pump", (22 patients) surgery. Serum levels of sCD163 in venous blood samples taken before and after surgery, and during an early postoperative period, were evaluated by Macro 163(TM) diagnostic kit (IQ Products, Groningen, NL). RESULTS: Compared to the preoperative levels ("on-pump"; 344 ng/mL, "off-pump"; 314.5 ng/mL, mini-invasive "on-pump"; 336.5 ng/mL) serum levels were elevated at the finish of surgery, reaching maximum at the 1(st) postoperative day ("onpump"; 658 ng/mL; p<0.05, "off-pump"; 810.5 ng/mL; p<0.01; mini-invasive "on-pump"; 663 ng/mL; non-significant).No significant differences regarding the serum levels of sCD163 between different surgical approaches were found. CONCLUSION: Serum level of sCD163 scavenger molecule for hemoglobin is elevated at the end of surgery and at the 1(st) postoperative day, being little influenced by cardiopulmonary bypass.

Haptoglobin is a glycoprotein involved in the acute phase response. Previously we reported that haptoglobin gene expression was up-regulated during dietary restriction in young female rats. The present study aimed at determining whether chronic dietary restriction affects haptoglobin blood levels through changing levels and/or activities of IL-6-related transcription factors STAT and C/EBP in the liver as is the case during the acute phase response. To this end, we compared a female Wistar rat model of 50% 6-week-long dietary restriction with the standard laboratory model for the acute phase response induced by turpentine administration. During the turpentine-induced acute phase response, the transitory 5.4-fold increase of rat haptoglobin expression was accompanied by a prominent rise of serum IL-6 concentration and the increased binding of STAT3 and 35kD C/EBPbeta/LAP transcription factors to the haptoglobin gene hormone-responsive element. Results obtained after immunoblotting and DNA affinity chromatography (using hormone-responsive element) suggest that the stable 1.7-fold increase of serum haptoglobin level during dietary restriction was the result of increased amounts and activities of constitutive transcription factors C/EBPalpha and STAT5b, and to a smaller extent of STAT3. When dietary restriction rats were administered turpentine, a 8.7-fold increase in haptoglobin expression was followed by a considerable increase in the amount and hormone-responsive element binding activity of STAT3 but not 35kD C/EBPbeta/LAP. We concluded that haptoglobin gene up-regulation during chronic dietary restriction was regulated by different mechanisms than during the acute phase response, and that it depended on the amount(s) and activit(ies) of transcription factor(s) that characterize low-grade inflammatory conditions.
