DOI: 10.1016/j.ymeth.2016.09.013
Abstract: Neutrophils or polymorphonuclear cells (PMN) eliminate bacteria via phagocytosis and/or NETosis. Apart from these conventional roles, PMN also have immune-regulatory functions. They can transdifferentiate and upregulate MHCII as well as ligands for costimulatory receptors which… read more here.

Abstract: The HIV-1 glycoprotein gp41 critically mediates CD4+ T-cell infection by HIV-1 during viral entry, assembly, and release. Although multiple immune-regulatory activities of gp41 have been reported, the underlying mechanisms of these activities remain poorly understood.… read more here.

DOI: 10.1073/pnas.2118816119
Abstract: Significance Cancers and chronic infectious pathogens often evade immune-mediated elimination by suppressing T cell function via engaging inhibitory receptors expressed on T cells. The phospholipid lysophosphatidic acid (LPA) is often increased systemically from basal concentrations… read more here.

DOI: 10.1126/science.abp8933
Abstract: Cytotoxic T lymphocytes (CTLs) kill virus-infected and cancer cells through T cell receptor (TCR) recognition. How CTLs terminate signaling and disengage to allow serial killing has remained a mystery. TCR activation triggers membrane specialization within… read more here.

DOI: 10.1172/jci.insight.94298
Abstract: Patients deficient in the guanine nucleotide exchange factor DOCK8 have decreased numbers and impaired in vitro function of Tregs and make autoantibodies, but they seldom develop autoimmunity. We show that, similarly, Dock8-/- mice have decreased… read more here.
