Our experiments examined T-lymphocyte numbers and effector-functions in peritoneal contamination and infection (PCI) a mouse model of sepsis. One of our main questions was how T-lymphocytes reconstitute after sepsis-induced lymphopenia. We investigated the quantitative and qualitative recovery of T ...

Exposure to inflammatory cytokines driven by bystander cytokines can have profound effects on the function of memory CD8 T cells. Here we transferred a 1-5X10^4 of P14 TCR-tg T cells (specific for gp33-41 of LCMV) on day -1 followed by infection with 2X10^5 PFU of LCMV Armstrong ip to generate memor...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system with marked heterogeneity in several aspects including pathological processes. Four histopathological patterns of MS have been described. Pattern II is characterized by antibody and complement depos...

Induced Treg (iTreg) cells are essential for tolerance and can be used therapeutically, yet their stability in vivo and mechanisms of suppression are unresolved. Here, we used a treatment model of colitis to examine the role of autologous IL-10 in iTreg cell function. Mice treated with IL-10+/+ iTr...

An unresolved issue in immunology is the extent to which inflammatory effects are needed for robust T cell responses. In this study, mice were immunized by iv injection using either high toxicity lipopolysaccharide (LPS) or low toxicity monophosphoryl lipid A (MPL) as adjuvant. Six hours after iv ...

The Rac nucleotide Exchange Factor (Rac-GEF) P-Rex1 is highly expressed in breast cancer, specifically in the luminal subtype, and is an essential mediator of actin cytoskeleton reorganization and cell migratory responses induced by ErbB and other tyrosine-kinase receptors. Heregulin, a growth facto...
