![]() ![]() ![]() All granulocyte forms have the capacity to ingest virus particles, bacteria, or other parasites. There are three different forms of granulocytes: basophils, eosinophils, and neutrophils. They comprise about 60% of all white blood cells. Granulocytes are a type of white blood cells. Macrophages provide a first line of defense in protecting the host from infection. They recognize and consequently destroy the target cell. Macrophages are large, specialized cells that are present in every tissue of the body. Upon infection or tissue damage, monocytes, one of the major groups of white blood cells, rapidly differentiate into macrophages. Macrophages (and their precursor cells, monocytes) are important cells of the immune system. A short list is mentioned below and on the following page. ![]() Every T cell type expresses different cell surface markers and secretes different cytokines. There are different types of T cells named helper T cell, killer T cell, and regulatory T cell (Treg). Thus, T cells are essential for the human immune system. T cells detect cellular abnormalities, directly destroy bacterially infected cells, and support other immune cells to produce antibodies. They perform a variety of functions in the blood system. CD20 also serves as a useful target for antibody-mediated therapeutic depletion of B cells. It is involved in the regulation of B-cell activation and proliferation. B cells go through several stages of development during exposure to antigens.ĬD20 is a B-lymphocyte surface molecule that is widely expressed during B-cell ontogeny, from early pre-B-cell developmental stages until final differentiation into plasma cells. B cells are produced in the bone marrow and migrate to the spleen and other secondary lymphoid tissues for maturation. B Cellsī cells (bursal or bone marrow-derived cells) are lymphocytes that play a pivotal role in the adaptive immune system and disruption of B cell function is a common hallmark of many different diseases. This catalog offers a detailed choice of the most commonly used cell markers and an extensive selection of antibodies used in immunology. Cell markers are helpful tools used to identify a specific immune cell population. The central points of immunology are: understanding, identifying, and distinguishing the many different immune cells that are essential for diagnosis and therapy. ![]() Although immunology covers all aspects of this complex network, the field is united by the immune cell. The human immune system contains a collection of different cell types and molecules that help to protect the body from toxins, viral infections, bacteria, and parasites. ![]()
