Cd207-flox Mouse

Cd207, also known as Langerin, is a C-type lectin receptor. It is specifically expressed on the surface of Langerhans cells (LCs) and is considered an LC-specific immunohistochemical marker. Langerin is involved in the formation of Birbeck granules in LCs, which are important for the specialized function of LCs in antigen capture and initiating specific immunity [4].

In Langerhans cell histiocytosis (LCH), the pathogenic cells are CD1a+/CD207+ cells resulting from the clonal expansion of myeloid precursors [1]. Monitoring circulating CD207+CD1a+ cells in LCH patients can help set a cellular score with minimal invasiveness, contributing to prognostic accuracy, early reactivation detection, and follow-up [3]. In Condyloma acuminatum, the fewer CD207 positive cells in skin lesions, the longer the disease course and the more frequent the recurrence, suggesting that CD207 expression level can be used as a new prognostic marker [2].

In conclusion, Cd207 is crucial for the function of Langerhans cells. Its role in diseases like Langerhans cell histiocytosis and Condyloma acuminatum shows its significance in understanding disease mechanisms and prognosis. Studies on Cd207 contribute to a better understanding of the related biological processes and disease conditions, potentially providing new strategies for diagnosis and treatment.
