A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response.T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface.
They are key to an experimental autologous cell therapy (Contego) for metastatic melanoma. [15] Autologous TIL therapy for metastatic melanoma has broad T cell recognition of both defined and undefined tumor antigens against all human leukocyte antigen (HLA) restrictions.
The neutrophil to lymphocyte ratio (NLR) reflects systemic inflammation, which plays an important role in the process of treating ischemic strokes.
Lymphocyte homing receptors are cell adhesion molecules [1] expressed on lymphocyte cell membranes that recognize addressins on target tissues. Lymphocyte homing refers to adhesion of the circulating lymphocytes in blood to specialized endothelial cells within lymphoid organs. [2]
In situ follicular lymphoma is an accumulation of monoclonal B cells (i.e. cells descendent from a single ancestral cell) in the germinal centers of lymphoid tissue. These cells commonly bear a pathological genomic abnormality, i.e. a translocation between position 32 on the long (i.e. "q") arm of chromosome 14 and position 21 on chromosome 18's q arm.
An image search engine is a search engine that is designed to find an image. The search can be based on keywords, a picture, or a web link to a picture. The results depend on the search criterion, such as metadata, distribution of color, shape, etc., and the search technique which the browser uses.
