KIR3DL1
KIR3DL1: A Guardian of Immune Surveillance
Description:
KIR3DL1 is a protein expressed on the surface of Natural Killer (NK) cells, specialized immune cells that recognize and eliminate infected or damaged cells. It belongs to the Killer cell Immunoglobulin-like Receptor (KIR) family and plays a pivotal role in the body's immune response.
Associated Diseases:
KIR3DL1 has been linked to several autoimmune and inflammatory diseases, including:
- Multiple Sclerosis (MS): Individuals with MS have decreased expression of KIR3DL1, which impairs NK cell function and contributes to disease progression.
- Rheumatoid Arthritis (RA): Patients with RA exhibit altered KIR3DL1 levels, affecting NK cell activity and inflammatory responses.
- Type 1 Diabetes (T1D): KIR3DL1 deficiency is associated with an increased risk of developing T1D, highlighting its role in controlling autoreactive immune responses.
Did you Know ?
Approximately 10-20% of the human population carries a specific variant of KIR3DL1 known as the "short tail" allele. This allele has been linked to enhanced NK cell cytotoxicity and protection against certain infections.
