Outline of Final Research Achievements

Myeloid cells act central roles in inflammatory responses. C-type lectin receptors (CLRs) are key players that are expressed mainly in these cells to orchestrate immune responses for maintaining immune homeostasis. These receptors recognize carbohydrate structures in microbes, including fungi, bacteria, viruses, and parasites, as pathogen-associated molecular patterns (PAMPs). Owing to the activities, the pleiotropic roles of CLRs has been suggested to have an important effect on homeostasis in the body. In this study, we found that collaboration of several C-type lectins are important in anti-fungal immunity.
