TNFα and IFNγ but Not Perforin Are Critical for CD8 T Cell-Mediated Protection against Pulmonary Yersinia pestis Infection
Pulmonary infection with the bacterium Yersinia pestis causes pneumonic plague, an often-fatal disease for which no vaccine is presently available. Antibody-mediated humoral immunity can protect mice against pulmonary Y. pestis infection, an experimental model of pneumonic plague. Little is known about the protective efficacy of cellular immunity. We investigated the cellular immune response to...
متن کاملDifferentially Expressed Potassium Channels Are Associated with Function of Human Effector Memory CD8+ T Cells
The voltage-gated potassium channel, Kv1.3, and the Ca2+-activated potassium channel, KCa3.1, regulate membrane potentials in T cells, thereby controlling T cell activation and cytokine production. However, little is known about the expression and function of potassium channels in human effector memory (EM) CD8+ T cells that can be further divided into functionally distinct subsets based on the...
متن کاملXenopus elav-like genes are differentially expressed during neurogenesis
In Xenopus, three neural-specific elav-like genes (ELGs) have been identified, elrB/Xel-1, elrC and elrD. With the aim to highlight possible differences in the regulation of these genes, we compared their expression patterns during development. We had previously shown that elrB is expressed from the early tailbud stage onwards, in both the central and peripheral nervous system. Here we show tha...
متن کاملCytotoxic T lymphocyte granules are secretory lysosomes, containing both perforin and granzymes
Cytotoxic T lymphocytes (CTL) contain granules that are exocytosed during specific interaction with target cells (TC). In this process, the granule contents, including the lethal protein perforin, as well as granzymes, a family of serine esterases, are delivered to the TC. Information regarding the routing of these proteins towards the granule and their exact localization within the granule is ...
متن کاملGranzymes are necessary for suppressive function of regulatory T cells
Purpose Regulatory T (Treg) cells are an essential subset of CD4+ T cells that induce and maintain immunological tolerance. Preclinical animal models have demonstrated that adoptive transfer of Treg cells can prevent or cure diabetes, multiple sclerosis (EAE), inflammatory bowel disease, lupus, arthritis, and graft versus host disease. Defects in Treg cell function and number have been describe...
