CLECL1
Clecl1 (C-type Lectin Domain Family 1, Member 1)
Description:
Clecl1, also known as myeloid inhibitory C-type lectin receptor, is a transmembrane protein expressed primarily on myeloid cells of the immune system, including macrophages, neutrophils, and dendritic cells. It belongs to the C-type lectin receptor superfamily, which recognizes carbohydrate structures on pathogens and immune cells.
Function:
Clecl1 acts as a pattern recognition receptor that binds to specific carbohydrates present on both microbial and self-antigens. This binding triggers intracellular signaling pathways that modulate immune responses. Clecl1 can promote phagocytosis (engulfment of pathogens by immune cells), suppress inflammatory responses, and regulate T cell activation.
Associated Diseases:
Dysregulation of Clecl1 expression or function has been linked to several diseases, including:
- Sepsis: Impaired Clecl1 function can contribute to excessive inflammation and organ damage during sepsis.
- Autoimmune disorders: Overexpression of Clecl1 has been observed in certain autoimmune conditions, such as rheumatoid arthritis and systemic lupus erythematosus.
- Cancer: Clecl1 can play a role in tumor progression and metastasis by promoting immune suppression.
Did you Know ?
Studies have shown that individuals with a genetic variant (single-nucleotide polymorphism) in the CLECL1 gene have an increased risk of developing severe sepsis.
