Detection of gene expression specific for different kind of immune cell populations can then be used to determine the degree of lymphocyte infiltration as has been shown in breast cancer. [13] An active immune environment within the tumor often indicates a better prognosis as can be determined by the Immunological constant of rejection .
Duodenal lymphocytosis, sometimes called lymphocytic duodenitis, lymphocytic duodenosis, or duodenal intraepithelial lymphocytosis, is a condition where an increased number of intra-epithelial lymphocytes is seen in biopsies of the duodenal mucosa when these are examined microscopically.
Infiltration in a medical context is the process of cells or substances moving across a barrier, typically a tissue barrier, into a place they are not normally found ...
The predictive value and prevalence of lymphovascular invasion is strongly dependent on the type of cancer. In other words, LVI in one type of cancer may be much less important than LVI in another type of cancer.
Jessner lymphocytic infiltrate of the skin is a cutaneous condition characterized by a persistent papular and plaque-like skin eruption which can occur on the neck, face and back and may re-occur. This is an uncommon skin disease and is a benign collection of lymph cells.
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 ...

The majority of IELs (80%) are CD3+, and over 75% of these also express CD8.IELs can be divided into two major subsets based on their CD8 coreceptor expression. [5] One subset of IELs typically express activation marker CD8αα and some IELs express CD8αβ + marker (CD8αβ promotes TCR activation, whereas CD8αα suppresses TCR signals).
