The development of inhibitors in patients with severe haemophilia A is a serious complication requiring long term immune tolerance therapy (ITT). ITT frequently requires implantable central venous access, mostly port catheters. Their use may be complicated by thrombosis and infection. We report on an 18 year old patient with severe haemophilia A who had developed a high-titre factor VIII inhibitor in the age of five years. ITT required the implantation of a port system. The postoperative course was complicated by severe septicaemia with congestive cardiac failure. The port catheter was removed due to recurrent fever after 26 days. Our patient developed dilative cardiomyopathy. ITT had to be stopped and was replaced by on demand therapy with an activated prothrombin complex concentrate. Cardiomyopathy resulted in congestive heart failure, severe ventricular arrhythmias and the death of the young man. In patients with haemophilia, dilative cardiomyopathy and development of inhibitors the possibility of cardiac transplantation should be evaluated before increasing inhibitors and the development of pulmonary hypertension exclude this therapeutical option.

Targeting immune cellular populations and transcription factors: unraveling the therapeutic potential of JQF for NAFLD.

Background: Non-alcoholic fatty liver disease (NAFLD) constitutes the most prevalent chronic liver disease worldwide. Progression to non-alcoholic steatohepatitis (NASH), the immune cell reservoir within the liver undergoes remodeling, exacerbating liver inflammation and potentially leading to liver fibrosis. Jiangtang Qingre Formula (JQF) is an effective prescription for the clinical treatment of NAFLD.

Introduction: Endoplasmic reticulum aminopeptidases 1 (ERAP1) and 2 (ERAP2) modulate a plethora of physiological processes for the maintenance of homeostasis in different cellular subsets at both intra and extracellular level.

Materials And Methods: In this frame, the extracellular supplementation of recombinant human (rh) ERAP1 and ERAP2 (300 ng/ml) was used to mimic the effect of stressor-induced secretion of ERAPs on neutrophils isolated from 5 healthy subjects. In these cells following 3 h or 24 h rhERAP stimulation by Western Blot, RT-qPCR, Elisa, Confocal microscopy, transwell migration assay, Oxygraphy and Flow Cytometry we assessed: i) rhERAP internalization; ii) activation; iii) migration; iv) oxygen consumption rate; v) reactive oxygen species (ROS) accumulation; granule release; vi) phagocytosis; and vii) autophagy.

Osmoregulation is essential for the survival of aquatic organisms, particularly teleost fish facing osmotic challenges in environments characterized by variable salinity. While the gills are known for ion exchange, the intestine's role in water and salt absorption is gaining attention. Here, we investigated the adaptive responses of the intestine to salinity stress in guppies (), observing significant morphological and transcriptomic alterations.

The liver is a unique organ where immunity can be biased toward ineffective response notably in the context of viral infections. Chronic viral hepatitis depends on the inability of the T-cell immune response to eradicate antigen. In the case of recombinant Adeno-Associated-Virus, used for therapeutic gene transfer, conflicting reports describe tolerance induction to different transgene products while other studies have shown conventional cytotoxic CD8 T cell responses with a rapid loss of transgene expression.
