White blood cells (scientific name leukocytes), also called immune cells or immunocytes, are cells of the immune system that are involved in protecting...

Cellular immunity, also known as cell-mediated immunity, is an immune response that does not rely on the production of antibodies. Rather, cell-mediated...

of cancer. Cell-based immunotherapies are effective for some cancers. Immune effector cells such as lymphocytes, macrophages, dendritic cells, natural killer...

molecules and cells to perform their functions. Nearly all organisms have some kind of immune system. Bacteria have a rudimentary immune system in the...

Beyond vertebrates). The major functions of the innate immune system are to: recruit immune cells to infection sites by producing chemical factors, including...

A non-specific immune cell is an immune cell (such as a macrophage, neutrophil, or dendritic cell) that responds to many antigens, not just one antigen...

cell (leukocyte) in the immune system of most vertebrates. Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for...

helper cells (Th cells), also known as CD4+ cells or CD4-positive cells, are a type of T cell that play an important role in the adaptive immune system...

Natural killer cells, also known as NK cells, are a type of cytotoxic lymphocyte critical to the innate immune system. They are a kind of large granular...

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...

systemic cells and processes that eliminate pathogens or prevent their growth. The acquired immune system is one of the two main immunity strategies...

pathogen . Components of the innate immune response include physical barriers like the skin and mucous membranes, immune cells such as neutrophils, macrophages...

This is a list of immune cells, also known as white blood cells, white cells, leukocytes, or leucocytes. They are cells involved in protecting the body...

It also decreases cancer immunosurveillance, in which the immune system scans the body's cells and kills neoplastic ones. They are also more susceptible...

cancer cells often have tumor antigens, molecules on their surface that can bind to antibody proteins or T-cell receptors, triggering an immune system...

Common variable immunodeficiency (CVID) is an inborn immune disorder characterized by recurrent infections and low antibody levels, specifically in immunoglobulin...

A dendritic cell (DC) is an antigen-presenting cell (also known as an accessory cell) of the mammalian immune system. A DC's main function is to process...

antibodies can effectively "tag" a microbe or an infected cell for attack by other parts of the immune system, or can neutralize it directly (for example, by...

immunity is named so because it involves substances found in the humors, or body fluids. It contrasts with cell-mediated immunity. Humoral immunity is...

antibodies by the immune system. Passive immunity is acquired through the transfer of antibodies or activated T-cells derived from an immune host either artificially...
