The immunoglobulin heavy chain variable region gene (IgHV) mutation status has been an established prognostic factor in patients with CLL. A cutoff of 2% deviation or 98% sequence identity to germline in the IgHV sequence has been routinely used as a prognostic marker [2].

Nivolumab is a human immunoglobulin G4 (IgG4) monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response, resulting in decreased tumor growth.

The lymphocytes developed in the BM (B-cells) have as their final task the production of Ag-specific immunoglobulins (Ig), which function as antibodies (Ab). Ig are proteins secreted by or present on the surface of B-cells, assembled from identical couples of heavy (H) and light (L) chains.

Atypical lymphocytosis in children. A complete blood count performed during the evaluation of a febrile or traumatized child may show the presence of atypical lymphocytosis. Although atypical lymphocytes occur in several conditions, they are most closely associated with infectious mononucleosis (IM).

The immunoglobulin heavy chain (IgH) is the large polypeptide subunit of an antibody (immunoglobulin). In human genome, the IgH gene loci are on chromosome 14. A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains.

In majority of cases, this usually involves a disease transformation to an aggressive non-Hodgkin lymphoma, multiple myeloma or prolymphocytic lymphoma [Bracey et al. 1989]. CLL patients can rarely develop acute myeloid leukemia (AML) [Bracey et al.

Immature B cells express CD19, CD 20, CD34, CD38, and CD45R, but not IgM. For most mature B cells the key markers include IgM and CD19, a protein receptor for antigens (Kaminski DA. ... Plasma B cells lose CD19 expression, but gain CD78, which is used to quantify these cells.

Signs and Symptoms An unexplained elevated white blood cell (lymphocyte) count is the most common finding that leads a doctor to consider a CLL diagnosis. Enlarged spleen or liver (This can cause a feeling of fullness.)

The CD5+B lymphocytes have been postulated to produce autoantibodies. CLL patients may demonstrate features of autoimmunity including autoimmune hemolytic anemia. However, the origin of the autoantibodies causing the hemolysis is not clear.

Immune Mediated Haemolytic Anaemia (IMHA) is a condition where the body's immune system, which normally fights infection, starts to damage and destroy red blood cells. This results in the affected animal becoming anaemic (having a low red blood cell count).

Immunoglobulin G (IgG) is one type of antibody that is "tailor-made" to attack a specific disease-causing agent (called a pathogen). Herpes IgG is the type produced when an HSV infection occurs. The IgG test is not the only antibody test used to detect HSV.

Immunoglobulin (also called gamma globulin or immune globulin) is a substance made from human blood plasma. The plasma, processed from donated human blood, contains antibodies that protect the body against diseases.

Adult T-cell leukaemia/lymphoma (ATLL) is a potentially aggressive type of mature T-cell non-Hodgkin lymphoma. It is linked to the viral infection, HTLV-1 (human T-cell lymphotropic virus 1). ATLL cancerous T-cells are found in the peripheral circulating blood (leukaemia), in the lymph nodes (lymphoma), or in both.

Serum antinuclear antibodies (ANAs) are positive in some patients with chronic lymphocytic leukemia (CLL), but the prognostic value of ANAs remains unknown. The aim of this study was to evaluate the role of ANAs as a prognostic factor in CLL.

Chronic lymphocytic leukemia (CLL) is a type of cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made. The term "chronic" in chronic lymphocytic leukemia comes from the fact that it typically progresses more slowly than other types of leukemia.
