We studied the effect of non-selective intracoronary transplantation of bone marrow mononuclears on day 30 after acute coronary infarction on angiogenesis in rats. On days 14 and 30 after transplantation of mononuclear cells, stable formation of new vessels was observed. The number of venules considerably increased after transplantation of mononuclear cells, which was seen from increased volume density of blood vessels and their caliber. Stable vascularization after transplantation of mononuclear cells improves blood supply, which is essential for reparation of the myocardium.

Background: Metabolic syndrome represents a pancreatic ductal adenocarcinoma (PDAC) risk factor. Metabolic alterations favor PDAC onset, which occurs early upon dysmetabolism. Pancreatic neoplastic lesions evolve within a dense desmoplastic stroma, consisting in abundant extracellular matrix settled by cancer associated fibroblasts (CAFs).

Background: Gene-edited pigs for xenotransplantation usually contain one or more transgenes encoding human complement regulatory proteins (CRPs). Because of species differences, human CRP(s) expressed in gene-edited pigs may have difficulty inhibiting the activation of exogenous rabbit complement added to a complement-dependent cytotoxicity (CDC) assay. The use of human complement instead of rabbit complement in CDC experiments may more accurately reflect the actual regulatory activity of human CRP(s).

Previous studies in sports science suggested that regular exercise has a positive impact on human health. However, the effects of endurance sports and their underlying mechanisms are still not completely understood. One of the main debates regards the modulation of immune dynamics in high-intensity exercise.

CAR-T cell therapies have risen to prominence over the last decade, and their indications are increasing with several products approved as early as second line in Large B Cell non-Hodgkin Lymphomas. Their major toxicities are the cytokine release syndrome (CRS) and the Immune-effector Cell Associated Neurotoxicity Syndrome (ICANS). These entities involve a hyperinflammatory cascade which is amplified through the mononuclear phagocytic system (MPS).

Idiopathic inflammatory myopathies (IIMs) are a group of autoimmune disorders characterized by immune cell infiltration of muscle tissue accompanied by inflammation. Treatment of IIMs is challenging, with few effective therapeutic options due to the lack of appropriate models that successfully recapitulate the features of IIMs observed in humans. In the present study, we demonstrate that immunodeficient mice transplanted with human peripheral blood mononuclear cells (hPBMCs) exhibit the key pathologic features of myositis observed in humans and develop graft-versus-host disease.
