CD86

What is cd86 protein?

CD86, also known as B7-2, is a protein that is primarily expressed on the surface of antigen-presenting cells (APCs), including dendritic cells, macrophages, and B cells. It is a co-stimulatory molecule that plays a crucial role in the immune response.

The main function of CD86 is to interact with its receptor, CD28, on T cells. This interaction provides a co-stimulatory signal necessary for the activation and proliferation of T cells. CD86 is involved in promoting T cell differentiation into effector cells and enhancing their cytokine production.

Furthermore, CD86 can also bind to an alternative receptor, CTLA-4, which has inhibitory functions. The binding of CD86 to CTLA-4 regulates T cell activation and helps maintain immune homeostasis by preventing excessive immune responses.

What is the function of cd86 protein?

CD86 is essential for efficient antigen presentation and the initiation of adaptive immune responses. It contributes to the activation and regulation of various immune cells, making it a crucial player in immune system function.

Cd86 related signaling pathway

CD86 signaling pathway involves the activation of kinases such as PI3K (phosphatidylinositol 3-kinase) and Akt (protein kinase B), which regulate multiple downstream signaling events. Activation of these kinases leads to the activation of the transcription factor NF-κB, which promotes the expression of pro-inflammatory cytokines and other immune-related genes.

In addition to its role in T cell co-stimulation, CD86 has also been implicated in other cellular processes, including B cell activation, antibody production, and the induction of regulatory T cells (Tregs). It plays a crucial role in modulating immune responses and maintaining immune homeostasis.

Aberrant CD86 signaling has been associated with various autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and autoimmune hepatitis. Additionally, dysregulation of CD86 expression has been observed in certain types of cancer, suggesting a potential role in tumor immune evasion.

Cd86 Related Diseases

• Fibrodysplasia Ossificans Progressiva (FOP): Also known as "Stone Man Syndrome," this is a rare disease in which the body's soft tissues progressively turn into bone. BMP2, along with other proteins, play a significant role in the abnormal bone growth.
• Heterotopic Ossification (HO): This condition also involves abnormal bone growth in areas like muscles and tendons. Increased levels of BMP2 can kick start the process of ossification, leading to this condition.
• Congenital Heart Defects: Children born with heart defects may have mutations in the BMP2 gene. It plays an important role in heart development, and disruptions can cause defects.

Biomedical Application of cd86 Protein

The biomedical applications of CD86 are primarily focused on therapeutic interventions aimed at modulating immune responses. Strategies targeting CD86, such as blocking antibodies or small molecule inhibitors, are being explored for the treatment of autoimmune diseases and as potential immunotherapies for cancer. Additionally, understanding the CD86 signaling pathway provides insights into the regulation of immune responses and potential targets for intervention.

CD86 has several biochemical functions, for example, coreceptor activity,protein binding,receptor activity. Some of the functions are cooperated with other proteins, some of the functions could acted by CD86 itself. We selected most functions CD86 had, and list some proteins which have the same functions with CD86. You can find most of the proteins on our site.
