CD19 is present on B cells from earliest recognizable B-lineage cells during development to B-cell blasts but is lost on maturation to plasma cells. Its expression in mature B cell are Various - Highlights CD 19 (CD) higher than that in immature B cells.

Lymphoma is a group of blood cancers that develop from lymphocytes. Many B cells mature into what are called plasma cells that produce antibodies proteins necessary to fight off infections while other B cells mature into memory B cells. B-cells fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells.

B-lymphocytes and Various - Highlights CD 19 (CD) have what may be described as a love-hate relationship. For example, B-cells sometimes inhibit tumor development by producing antibodies that may attack cancer cells or oncogenic viruses, such as human papillomavirus HPVVarious - Highlights CD 19 (CD) is responsible for most cervical, anal, penile and other reproductive cancers.

Other times, regulatory B-cells may release immune-suppressive cytokines that stifle an anti-tumor response. Also, B-cells are far more likely than T-cells to mutate into a liquid cancer such as chronic lymphocytic leukemia CLL or B-cell lymphoma. CD19 protein appears early during B-cell maturation and is found during all stages of B-cell maturation, including plasma cells.

CD19 is useful as an additional marker of B cell lineage in leukemias and lymphomas. Expression of CD19 may be seen in some acute myeloid leukemias. CD19 is thus critical for the body to mount an optimal immune response. Follicular lymphoma, for example, has a lower CD19 level more frequently than any Various - Highlights CD 19 (CD) lymphoma subtypes. Very rare.

The most current experimental anti-CD19 immunotoxins in development work by exploiting the widespread presence of CD19 on B cells, with expression highly conserved in most neoplastic B cells, to direct treatment specifically towards B-cell cancers.

This suggests that CD19 and its downstream signaling may be a more attractive therapeutic target than initially suspected. CAR T cells are more effective than anti-CD19 immunotoxins because they can proliferate and remain in the body for a longer period of time.

  2. The CD19 antigen (aka B-lymphocyte antigen CD19 or Cluster of Differentiation 19) plays an important role in clinical’s a protein found on the surface of B-cells, a type of white blood cell.. Since CD19 is a hallmark of B-cells, the protein has been used to diagnose cancers that arise from this type of cell - notably B-cell lymphomas. CD19 has also been implicated in .

  5. So because HIV damages the immune system. So there are the tests which can assess the immune system of the patient so these tests are called cd4 count and viral load. CD-4 is nothing but it is a sub site of T-cell. So the normal CD count for a patient would range from which is a normal range. The other test which is available is viral.
