HAVCR2
Description
The HAVCR2 gene, also known as TIM-3, encodes a protein that plays a critical role in regulating the immune system. It acts as an immune checkpoint, dampening the activity of T cells, a type of white blood cell essential for fighting infections. This function is particularly important in preventing autoimmune diseases, where the immune system attacks healthy tissues. However, TIM-3 also contributes to the suppression of anti-tumor immune responses, allowing cancer cells to escape destruction.
Associated Diseases
- Autoimmune diseases like systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS)
- Infectious diseases such as viral infections (e.g., influenza, hepatitis C)
- Cancer, especially in the context of tumor immune evasion
- Allergic diseases, including asthma and atopic dermatitis
Did you know?
The HAVCR2 gene was initially discovered in a study of hepatitis A virus (HAV) infection, hence its name. However, its role in immune regulation extends far beyond this initial observation.
