Summary
CD94 protein expression varies across T/NK-cell neoplasms. High CD94 levels in NK-cell neoplasms and some T-cell lymphomas suggest potential targets for new therapies.
Area of Science:
- Hematology
- Immunology
- Oncology
Background:
- T-cell and NK-cell lymphomas/leukemias are diverse and lack effective treatments.
- CD94-targeted therapies are being investigated, but CD94 expression data in these cancers is limited.
Purpose of the Study:
- To investigate CD94 protein expression in reactive T/NK-cells and various T/NK-cell neoplasms.
- To assess the potential of CD94 as a therapeutic target in these malignancies.
Main Methods:
- Flow cytometry was used to analyze CD94 protein expression.
- Studied 15 patients with reactive T/NK-cell proliferations and 124 patients with T/NK-cell neoplasms.
Main Results:
- High CD94 expression was found in reactive NK-cells and NK-cell neoplasms.
- CD94 was expressed in hepatosplenic T-cell lymphoma and some T-cell large granular lymphocytic leukemia cases.
- Most T-cell prolymphocytic leukemia and peripheral T-cell lymphoma cases lacked CD94 expression.
Conclusions:
- CD94 expression is heterogeneous across T/NK-cell neoplasms.
- Certain neoplasms exhibit high CD94 expression, indicating potential therapeutic vulnerability to CD94-targeted agents.

13.5K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

01:24T Cell Types and Functions
1.7K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:23Cells of the Adaptive Immune Response
7.3K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

5.5K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
