T RM cells express granzyme B which helps limit the spread of pathogens at the site of infection. Also, phenotypic and functional diversity is not only in T RM from different tissues, but it could be found in various T RM subsets within the same tissue. For example, CD49a distinguishes CD8 + T RM subsets with different functions
Antigen-specific memory T cells specific to viruses or other microbial molecules can be found in both central memory T cells (T CM) and effector memory T cells (T EM) subsets. . Although most information is currently based on observations in the cytotoxic T cells (CD8-positive) subset, similar populations appear to exist for both the helper T cells (CD4-positive) and the cytotoxic T ce
The concept of the tumor microenvironment (TME) dates back to 1863 when Rudolf Virchow established a connection between inflammation and cancer. However, it was not until 1889 that Stephen Paget's seed and soil theory introduced the important role of TME in cancer metastasis, highlighting the intricate relationship between tumors and their surrounding microenvironment.
A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei. In humans, lymphocytes make up ...

After that, they present these peptides in complexes together with their MHC molecules on their cell surface. DCs are also the only cell type which can activate naïve T cells and induce antigen-specific immune responses. [6] [7] Therefore, their role is crucially important in balance between tolerance and immune response.
T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
Whole-cell pertussis vaccine stimulates natural infection better than the acellular pertussis vaccine. [4] [5]Even though cell-mediated immunity persists in patients received with the acellular pertussis vaccine, stronger lymphocytic proliferation, specifically memory T helper 1 cell and T helper 17 cells and cytokine responses are observed in patients received with the whole cell pertussis ...
