Abstract There are two cell lineages of mammalian melanin pigment cells, one that leads to retinal pigment epithelium (RPE) cells in the eye from the optic cup and the other leading to melanocytes from vertebrate-specific neural crest cells. Melanocyte precursors have high mobility and migrate and settle into various tissues and organs, including the skin, choroid, inner ear, heart, brain, adipose tissue, lung, etc. It is well known that RPE cells are essential for visual acuity and that melanocytes in the skin provide protection against UV-damage. So, what is the function of extracutaneous melanocytes that are distributed elsewhere in the body where only very small amounts of light illuminate their existence? Here I would like to briefly introduce our research history and then discuss the important roles of melanocytes in the inner ear that are indispensable for hearing ability and those in the choroid where they seem to contribute to maintaining the structures of their habitats.

Abstract Secretory immunoglobulin A (SIgA) is predominant antibody secreted into the gut relating to maintain gut homeostasis. In the present study, we focused on the SIgA coating of gut bacteria as a mucosal immune response affecting the gut bacteria following a high-fat diet (HFD). This study newly showed that the level of SIgA coating of gut bacteria was significantly decreased in HFD-fed mice than normal-fat diet (NFD)-fed mice. Furthermore, we found that the relative abundances of gut bacteria were significantly negatively or positively correlated with the level of SIgA coating of gut bacteria in NFD-fed and HFD-fed mice. Our observations suggest that a decrease in the level of SIgA coating of the gut bacteria through a HFD might relate to HFD-induced changes in bacterial composition.
