| Outline of Final Research Achievements |
C-type lectin receptors are a large family of transmembrane proteins containing extracellular C-type lectin-like carbohydrate-recognition domain(s) and signal transduction region(s), i.e., immunoreceptor tyrosine-based activation motif (ITAM) and immunoreceptor tyrosine-based inhibitory motif (ITIM). Although ITAM-coupling CLRs are best-characterized as direct receptors for fungi, the role of ITIM-bearing CLRs has been poorly understood. In this study, we found that a soluble form of inhibitory-type CLRs bound to Candida species. Furthermore, inhibitory-type CLRs mediated inflammatory cytokine production in macrophages and neutrophils following stimulation with those fungi. These data suggest that inhibitory-type CLRs play an important role in immune responses to fungal infection.
