T cell memory in Capri

Memory T Cell Migration

Immunological memory is a key feature of adaptive immunity. It provides the organism with long-lived and robust protection against infection. In organ transplantation, memory T cells pose a significant threat by causing allograft rejection that is generally resistant to immunosuppressive therapy. Therefore, a more thorough understanding of memory T cell biology is needed to improve the survival...

TCR Signaling in T Cell Memory

T cell memory plays a critical role in our protection against pathogens and tumors. The antigen and its interaction with the T cell receptor (TCR) is one of the initiating elements that shape T cell memory together with inflammation and costimulation. Over the last decade, several transcription factors and signaling pathways that support memory programing have been identified. However, how TCR ...

Mitochondrial Networking in T Cell Memory

T-lymphocytes show large changes in ATP demand and nutrient utilization, imposed by their different roles as T memory and T effector cells. Therefore, T cell remodeling represents a bioenergetic challenge to mitochondria. New work from Buck et al. links changes in mitochondrial shape to T cell fate choice.

CAPRI to the Plasma Membrane CD28 Inhibits T Cell Adhesion by Recruiting

Superior T memory stem cell persistence supports long-lived T cell memory.

Long-lived memory T cells are able to persist in the host in the absence of antigen; however, the mechanism by which they are maintained is not well understood. Recently, a subset of human T cells, stem cell memory T cells (TSCM cells), was shown to be self-renewing and multipotent, thereby providing a potential reservoir for T cell memory throughout life. However, their in vivo dynamics and ho...
