Human epithelial type 2 (HEp-2) cells, considered to originate from a human laryngeal carcinoma, allow recognition of over 30 different nuclear and cytoplasmic patterns that are given by upwards of 50 different autoantibodies are associated with various autoimmune conditions.

The Class I MHC molecules are found on all nucleated cells in the body (including cells expressing Class II MHC such as antigen presenting cells, dendritic cells, macrophages, and B cells), but are not found on non-nucleated cells such as red blood cells.

Hepatitis is a virus that causes liver inflammation. Different strains of hepatitis exist, including hepatitis A, B, C, and D. The most common types of hepatitis are A, B, and C. Hepatitis A is usually a short-term infection while hepatitis B and C can cause long-term, or chronic, infections.

Hepatitis C is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis C virus (HCV) spreads through contaminated blood.

Lymphocytes are one of the main types of immune cells. Lymphocytes are divided mainly into B and T cells. B lymphocytes produce antibodies - proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them. ... Each plasma cell is essentially a factory for producing antibody.

Top 10 Things to Know About Lymphocytes Lymphocytes are a kind of white blood cell (WBC). Lymphocytes are cells of the immune system and help fight infection. Lymphocytes live in lymph nodes, but also in the bloodstream and all over the body. Lymphocytes come in two main types: B-cells and T-cells.

Viral infections of the liver that are classified as hepatitis include hepatitis A, B, C, D, and E. A different virus is responsible for each type of virally transmitted hepatitis. Hepatitis A is always an acute, short-term disease, while hepatitis B, C, and D are most likely to become ongoing and chronic.

Kupffer cells are the major phagocytic cell of the liver. Therefore, any particulate material that may be injected intravascularly into an animal may be found in this cell type.

T cells are a type of white blood cell called lymphocytes. These cells fight off diseases. The two categories of lymphocytes are T cells and B cells. The T cells respond to viral infections and boost immune function of other cells, while the B cells fight bacterial infections.

What do T-cells do? There are two main types of T-cells: helper T-cells and killer T-cells. Helper T-cells stimulate B-cells to make antibodies and help killer cells develop.

MHC class I molecules are one of two primary classes of major histocompatibility complex (MHC) molecules (the other being MHC class II) and are found on the cell surface of all nucleated cells in the bodies of vertebrates. They also occur on platelets, but not on red blood cells.

Hepatitis B immune globulin (HBIg) provides immediate, short-term protection against hepatitis B infection. HBIg has large amounts of hepatitis B antibodies taken from donated human blood. Antibodies are proteins that a person's immune system makes to fight germs, such as bacteria and viruses like hepatitis B.

A large number of clinical studies have shown that chronic HBV persistent infection causes the dysfunction of innate and adaptive immune response involving monocytes/macrophages, dendritic cells, natural killer (NK) cells, T cells.

Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in tissue culture taken from an aborted female fetus.

This test looks for antibodies called IgM in your blood. The test is used to find out whether you are actively infected with the hepatitis B virus (HBV). HBV has a central core and a surrounding envelope. Your immune system makes IgM antibodies to the core of HBV during the active stage of infection.

Autoimmune hepatitis is a rare disorder that affects females 4 times as often as males. Type 1 is more common and is usually diagnosed in adults. Type 2 is more common in children and often involves a more severe disease process.
