The immune synapse provides an important structure for communication with immune cells. Studies on immune synapses formed by cytotoxic T lymphocytes (CTLs) highlight the dynamic changes and specialised mechanisms required to facilitate focal signalling and polarised secretion in immune cells. In this Cell Science at a Glance article and the accompanying poster, we illustrate the different steps...
conclusions this study suggests that the il-7 level of chb patients may be related to tfh cells. in chb patients, il-7 possibly increases the level of tfh cells and hbv-specific cellular immune responses and thereby reduces the hbv dna level. background in patients with chronic hepatitis b (chb), the relation of interkeukin-7 (il-7) to either the t follicular helper cells (tfh cells) or to a sp...
Most immunologists agree that CD8 T cells are important in controlling viruses, at least after the first week of infection – the time it takes for naive CD8 T cells to expand and differentiate into antiviral cytotoxic T lymphocytes (CTL). Nonetheless, CD8 T-cell measurements in HIV clinical studies show little relation to disease prognosis. There are two possible interpretations – either CD8 T ...
