Islet cell transplantation has limited effectiveness because of an instant blood-mediated inflammatory reaction (IBMIR) that occurs immediately after cell infusion and leads to dramatic β cell death. In intraportal islet transplantation models using mouse and human islets, we demonstrated that alpha-1 antitrypsin (AAT, Prolastin-C), a serine protease inhibitor used for the treatment of AAT deficiency, inhibits IBMIR and cytokine-induced inflammation in islets. In mice, more diabetic recipients reached normoglycemia after intraportal islet transplantation when they were treated with AAT compared to mice treated with saline...

A 58-year-old patient presented with a severe, episodic panniculitis of the upper legs. Necrosis of the fatty tissue and a suspected superinfection led to amputation of one leg. The panniculitis was caused by a hereditary deficiency of alpha-1 antitrypsin (AAT) due to a ZZ mutation of the AAT gene. Neutrophilic panniculitis is found in 0.1% of patients with the ZZ mutation and therefore is the rarest clinical manifestation of AAT deficiency. With the exception of mild COPD, the patient had no other typical clinical symptoms of AAT deficiency...

: Alpha1-antitrypsin deficiency (AATD) is a genetic disease, caused by mutation of the AAT gene. Accumulation of mutated AAT protein aggregates in hepatocytes leads to endoplasmic reticulum (ER) stress resulting in impairment of liver functions and in some cases hepatocellular carcinoma, whereas decline of AAT levels in sera is responsible for pulmonary emphysema. In critical cases of liver ailments, the only option for treatment is liver transplantation, whereas AAT replacement therapy is followed in case of emphysema...

Trypanosoma congolense and T. vivax are the main causative agents of animal African trypanosomosis (AAT), a disease which hinders livestock production throughout sub-Saharan Africa and in some parts of South America. Although two trypanocidal drugs are currently available, the level of treatment is low due to the difficulty in diagnosing the disease in the field. The major clinical signs of AAT such as anaemia, weight loss, and infertility, are common to several other endemic livestock diseases. Current diagnostic methods, based on the visualization of the parasite in the blood, or on the detection of its DNA or the antibodies it triggers in the host, are not suitable for direct use in the field as they require specialized equipment and personnel...

BACKGROUND: African animal trypanosomosis (AAT), transmitted by tsetse flies and tick-borne diseases are the main constraints to livestock production in sub-Saharan Africa. Vector control methods such as pour-on offer individual protection against ticks but not against tsetse so far, for which protection has always been communal, through a reduction of their density. The latter requires the treatment of a large part of the herd in a given landscape and is not instantaneous. METHODOLOGY/PRINCIPAL FINDINGS: Two prospective surveys were conducted to evaluate the efficacy and persistence of a pour-on formulation composed of cypermetrhin, chlorpyrifos, piperonyl butoxid and citronella (Vectoclor, CEVA Santé Animal)...

Rice seed is a cost-effective bioreactor for the large-scale production of pharmaceuticals. However, convincing evidence of the immunogenicity of plant-specific glycans is still limited although plant-specific glycans are considered potential allergic antigens. In the present study, we found that the α-1,3-fucose content of the glycoprotein produced from rice seed was much lower than that in leaf, and conversely, a higher β-1,2-xylose content was detected in seed than that in leaf. We detected the α-1,6-fucose content in the glutelin and recombinant human α1-antitrypsin (OsrAAT)...

African animal trypanosomosis (AAT) is a parasitic disease that causes serious economic losses in livestock from anemia, loss of condition, emaciation and death in untreated cases. It is one of the major constraints to improved livestock production and productivity in Ethiopia. Entomological and parasitological surveys were conducted in the Omo-Ghibe tsetse belt of south Ethiopia to estimate the prevalence of bovine trypanosomosis and the apparent tsetse density (AD), and identify the potential risk factors...

Acute aortic thrombosis (AAT) is a rare life threatening event that leads to a sudden occlusion of the aorta. The mortality and morbidity of AAT is still high despite modern surgical techniques. Usually it is the result of a large saddle embolus to the aortic bifurcation, in situ thrombosis of an atherosclerotic aorta or acute occlusion of an abdominal aortic aneurysm. Clinical symptoms depend on the level of the aortic occlusion and can be mistaken for a stroke or similar neurological disease. The combination of age and advanced cardiac disease seems to be significant risks factors for AAT...

α1-antitrypsin (AAT), a circulating glycoprotein that rises during acute phase responses and healthy pregnancies, exhibits immunomodulatory properties in several T-cell-dependent immune pathologies. However, AAT does not directly interfere with T-cell responses; instead, it facilitates polarization of macrophages and dendritic cells towards M2-like and tolerogenic cells, respectively. AAT also allows NK cell responses against tumor cells, while attenuating DC-dependent induction of autoimmune NK cell activities...

Growth and development shortfalls that are disproportionately prevalent in children living in poor environmental conditions are postulated to result, at least in part, from abnormal gut function. Using data from The Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) longitudinal cohort study, we examine biomarkers of gut inflammation and permeability in relation to environmental exposures and feeding practices. Trends in the concentrations of three biomarkers, myeloperoxidase (MPO), neopterin (NEO), and α-1-antitrypsin (AAT), are described from an unparalleled number of fecal samples collected during the first 2 years of each child's life...

Glioblastoma (GBM) is one hypervascular and hypoxic tumor known among solid tumors. Antiangiogenic therapeutics (AATs) have been tested as an adjuvant to normalize blood vessels and control abnormal vasculature. Evidence of relapse exemplified in the progressive tumor growth following AAT reflects development of resistance to AATs. Here, we identified that GBM following AAT (Vatalanib) acquired an alternate mechanism to support tumor growth, called vascular mimicry (VM). We observed that Vatalanib induced VM vessels are positive for periodic acid-Schiff (PAS) matrix but devoid of any endothelium on the inner side and lined by tumor cells on the outer-side...

Peritransplant infusion of ethylene carbodiimide fixed donor splenocytes(ECDI-SPs) induces protection of islet and cardiac allografts. However, pro-inflammatory cytokine production during the peritransplantation period may negate the effect of ECDI-SPs. Therefore, we hypothesized that blocking pro-inflammatory cytokine secretion while increasing levels of anti-inflammatory cytokines would enhance the tolerance-induced efficacy of ECDI-SPs. The objective of this study was to determine the effectiveness of using ECDI-SPs combined with a short course of α1-antitrysin (AAT) for induction of tolerance...

An investigation was undertaken of the extent of genetic variation occurring within infectious bronchitis virus (IBV) vaccine strains following vaccination of day-old broiler chicks. Chicks were divided into seven groups, with two groups receiving single Massachusetts (Mass) vaccinations and the other four were inoculated with combinations of different IBV serotypes; Mass, 793B, D274, and Arkansas (Ark). The remaining group was maintained as an unvaccinated control. Following vaccination, swabs and tissues collected at intervals were pooled and RNA was extracted for detection of IBV by reverse transcription polymerase chain reaction (RT PCR)...

BACKGROUND AND OBJECTIVES: Alpha-1-antitrypsin deficiency (AATD) is associated with a high risk for the development of early-onset emphysema and liver disease. A large majority of subjects with severe AATD carry the ZZ genotype, which can be easily detected. Another rare pathologic variant, the Mmalton allele, causes a deficiency similar to that of the Z variant, but it is not easily recognizable and its detection seems to be underestimated. Therefore, we have included a rapid allele-specific genotyping assay for the detection of the Mmalton variant in the diagnostic algorithm of AATD used in our laboratory...

Chronic obstructive pulmonary disease (COPD) is caused by α1-antitrypsin deficiency (AATD) genetic susceptibility and exacerbated by infection. The current pilot study aimed at studying the combined effect of AATD and bacterial loads on the efficacy of COPD conventional pharmacotherapy. Fifty-nine subjects (29 controls and 30 COPD patients) were tested for genetic AATD and respiratory function. The bacterial loads were determined to the patients' group who were then given a long acting beta-agonist and corticosteroid inhaler for 6 months...
