Apoptotic Cell-Based Therapy for the Modification of the Inflammatory Response to Hemorrhagic Shock.

Introduction: Many trauma patients die from hemorrhagic shock in the military and civilian settings. Although two-thirds of hemorrhagic shock victims die of reasons other than exsanguination, such as the consequent cytokine storm, anti-inflammatory therapies failed to be utilized. Apoptotic cell-based treatments enhance innate ability to exert systemic immunomodulation as demonstrated in several clinical applications and hence might present a novel approach in hemorrhagic shock treatment.

Safety of Repeated Administration of Xenogeneic Human Apoptotic State (Allocetra-OTS) in Sprague Dawley Rats.

Apoptotic cells possess immunomodulatory effects that can be utilized to treat imbalanced immune conditions. Information on the preclinical safety of such treatment is sparse. In this study, the safety of apoptotic cells (Allocetra-OTS) was assessed in a GLP toxicological study on Sprague Dawley rats.

HLA binding-groove motifs are associated with myocarditis induction after Pfizer-BioNTech BNT162b2 vaccination.

Background And Aims: We found a higher incidence of myocarditis in young males who had received at least two Pfizer-BioNTech BNT162b2 vaccinations. The human leukocyte antigens (HLA) are known to play an important role in infectious and autoinflammatory diseases. We hypothesized that certain HLA alleles might be associated with vaccination-induced myocarditis.

Complement-membrane regulatory proteins are absent from the nodes of Ranvier in the peripheral nervous system.

Background: Homozygous CD59-deficient patients manifest with recurrent peripheral neuropathy resembling Guillain-Barré syndrome (GBS), hemolytic anemia and recurrent strokes. Variable mutations in CD59 leading to loss of function have been described and, overall, 17/18 of patients with any mutation presented with recurrent GBS. Here we determine the localization and possible role of membrane-bound complement regulators, including CD59, in the peripheral nervous systems (PNS) of mice and humans.
