T‐cell memory in tissues [PDF]

European Journal of Immunology, 2021
AbstractImmunological memory equips our immune system to respond faster and more effectively against reinfections. This acquired immunity was originally attributed to long‐lived, memory T and B cells with body wide access to peripheral and secondary lymphoid tissues.

Memory T Cells in Transplantation [PDF]

Current Transplantation Reports, 2014
Following infections and environmental exposures, memory T cells are generated that provide long-term protective immunity. Compared to their naïve T cell counterparts, memory T cells possess unique characteristics that endow them with the ability to quickly and robustly respond to foreign antigens. While such memory T cells are beneficial in protecting

Regulatory T cell memory [PDF]

Nature Reviews Immunology, 2015
Memory for antigen is a defining feature of adaptive immunity. Antigen-specific lymphocyte populations show an increase in number and function after antigen encounter and more rapidly re-expand upon subsequent antigen exposure. Studies of immune memory have primarily focused on effector B cells and T cells with microbial specificity, using prime ...

T cell memory [PDF]

Seminars in Immunology, 2009
There is perhaps no more important function of the adaptive immune system than to confer protection from reinfection by pathogens previously encountered and defeated. Within the T cell lineage, this property of remembering past antigenic threats resides in the small subset of memory cells which persist long after the disappearance of the short-lived ...

Vaccination Expands Antigen-Specific CD4+ Memory T Cells and Mobilizes Bystander Central Memory T Cells.

PLoS ONE, 2015
CD4+ T helper memory (Thmem) cells influence both natural and vaccine-boosted immunity, but mechanisms for their maintenance remain unclear. Pro-survival signals from the common gamma-chain cytokines, in particular IL-7, appear important.

Naïve, Effector, and Memory T cells Frequency in the Peripheral Blood of Healthy Men Following 4 Weeks of Intermittent Fasting [PDF]

International Journal of Nutrition Sciences
Background: Intermittent fasting (IF) is a 16/8 fasting model, which is supposed to recruit immune cells to the bone marrow, thus prevents immune exhaustion.

Memory T cells skew toward terminal differentiation in the CD8+ T cell population in patients with acute myeloid leukemia

Journal of Hematology & Oncology, 2018
Stem cell memory T (TSCM) and central memory T (TCM) cells can rapidly differentiate into effector memory (TEM) and terminal effector (TEF) T cells, and have the most potential for immunotherapy. In this study, we found that the frequency of TSCM and TCM

Memory T Cells in Flavivirus Vaccination

Vaccines, 2018
Flaviviruses include many medically important viruses, such as Dengue virus (DENV), Japanese encephalitis (JEV), tick-borne encephalitis (TBEV), West Nile (WNV), yellow fever (YFV), and Zika viruses (ZIKV).

Metabolic features of naïve and memory CD4⁺T cells in quiescence and during proliferation

Acta Biomedica Scientifica, 2022
Background. Memory CD4+ T cells proliferation is the basis for accelerated secondary immune response. The characteristics of memory CD4+ T cells providing their faster division compared to naive CD4+ T lymphocytes are poorly understood.

Distinct CD4−CD8− (Double-Negative) Memory T-Cell Subpopulations Are Associated With Indeterminate and Cardiac Clinical Forms of Chagas Disease

Frontiers in Immunology, 2021
CD4−CD8− (double-negative, DN) T cells are critical orchestrators of the cytokine network associated with the pathogenic inflammatory response in one of the deadliest cardiomyopathies known, Chagas heart disease, which is caused by Trypanosoma cruzi ...
