T cells

Cryopreservation constrains manufacturing and clinical delivery of immune cells such as NK and T cells. DMSO protects against freezing but becomes toxic at physiological temperatures; associated infusion morbidity can require washing or divided dosing that diminishes therapeutic effectiveness. This talk presents an alternative in which reversible, cytocompatible hydrogels encapsulate cells before freezing without DMSO. The speaker examines evidence that encapsulation cushions osmotic stress, suppresses kinetic and phase transitions, and reduces injury caused by extracellular ice growth and fus

…cord barrier allows immune cells infiltration secreting various cytokines that, together with neural cells particularly activated microglia, will spread inflammation and aggravate the neurological deficits. Infiltrated immune cells include neutrophils, monocyte-derived macrophages, and T-cells. Most of preclinical studies evaluated this response in two SCI models: contusion (CT) and transection (TS); having distinct mechanical action modes on spinal c

…Recent investigations reveal immune cells and lymphatic networks within the meninges, challenging their conventional role solely as a protective CNS barrier. Meningeal immune cells are increasingly recognized for their role in normal brain function and various neurological disorders. However, investigations into meningeal immunity in the context of H

…recruitment and activation of immune cells. T-cells in particular, have been shown to promote the evolution of secondary injury following ischemic stroke, however their role in SAH is still unclear.In this study we aimed to evaluate T-cells’ recruitment in the brain of SAH-injured mice to next investigate their specific role in injury progression.Adult C57BL/6J mice were subjected to SAH by blood injection in the prechiasmatic cistern or sham procedure and sacrificed at 3 or 7 days-post-injury (dpi). Sensorimotor deficits w

…show early signs of demyelination.5 T cells are also frequently present in advanced stages of MS and have a tissue resident memory (Trm) phenotype, are more frequently CD8+ then CD4+, are located perivascular, enriched in act

Immune cells and their derived molecules have major impact on brain function. Mice deficient in adaptive immunity have impaired cognitive and social function compared to that of wild-type mice. Importantly, replenishment of the T cell compartment in immune deficient mice restored proper brain function. Despite the robust influence on brain function, T cells are not found within the brain parenchyma, a fact that only adds more mystery into these enigmatic interactions between T cells and the brain. Our results suggest that meningeal space, surrounding the brain, is the site where CNS-associated
