Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.
Gamete release in the jellyfish Clytia is mediated by an opsin photopigment expressed in neurosecretory cells of the gonad ectoderm, which release an oocyte maturation hormone in response to light.
Autosomal dominant IRF4 deficiency is the first genetic etiology of Whipple's disease, a very rare chronic condition following a rather common infection by
Tropheryma whipplei.
A physical niche for neural stem cells is generated by the induction of the immediate skin epithelium, a process triggered by the arrival of neural precursors during sensory organ formation in medaka.
The expression of 'bilaterian-mesodermal’ genes changes the epithelial properties of the endomesoderm during the embryogenesis of the cnidarian Nematostella vectensis.
MR1T cells are human polyclonal T cells endowed with diverse effector functions in response to endogenous antigens presented by MHC-class 1-related molecule, MR1.
