Summary of "Opinion: Virtual memory CD8 T cells and lymphopenia-induced memory CD8 T cells represent a single subset: homeostatic memory T cells."

It is well established that lymphopenia induces the formation of the memory-phenotype T cells without the exposure to foreign antigens. More recently, the memory-phenotype antigen-inexperienced memory T cells were described in lymphoreplete mice and called virtual memory T cells. In this review, we compare multiple aspects of the biology of lymphopenia-induced memory T cells and virtual memory T cells, including cytokine requirements, the role of T-cell receptor specificity in the differentiation process, gene expression signature, and the immune response. Based on this comparison, we conclude that lymphopenia-induced memory T cells and virtual memory T cells most likely represent a single T-cell subset, for which we propose a term 'homeostatic memory T cells'.

Frontline Science: PECAM-1 (CD31) expression in naïve and memory, but not acutely activated, CD8 T cells.

Inhibitory cell surface proteins on T cells are often dynamically regulated, which contributes to their physiologic function. PECAM-1 (CD31) is an inhibitory receptor that facilitates TGF-β-mediated ...

Age-Related Decline in Primary CD8 T Cell Responses Is Associated with the Development of Senescence in Virtual Memory CD8 T Cells.

Age-associated decreases in primary CD8 T cell responses occur, in part, due to direct effects on naive CD8 T cells to reduce intrinsic functionality, but the precise nature of this defect remains u...

Medical and Biotech [MESH] Definitions

Type of declarative memory, consisting of personal memory in contrast to general knowledge.

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

Neurons in the ENTORHINAL CORTEX that project to the HIPPOCAMPUS. Grid cells and PLACE CELLS play a role in cognitive representation of spatial memory and navigation.

Neurological process involving the conversion of learned information into long-term memory.

Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI).
