Evolutionary transition from degenerate to non-redundant cytokine signaling networks supporting intrathymic T cell development

Project description:In mammals, T cell development in the thymus is critically dependent on the presence of the IL7 cytokine. Here, we describe the identification of the zebrafish ortholog of mammalian IL7, based on chromosomal localization, expression patterns, and deduced protein sequence. To examine the biological role of il7 in teleosts, we generated an il7 allele lacking most of its coding exons using CRISPR/Cas9-based mutagenesis. il7-deficient animals are viable, and exhibit no obvious signs of immune disorder. With respect to intrathymic T cell development, il7-deficiency is associated with only mild a reduction of thymocytes, contrasting with the much stronger reduction of T cell development il7r-deficient fish. Genetic interaction studies between il7 and crlf2(tslpr) suggest the contribution of an additional, as yet unidentified cytokine(s) to intrathymic T cell development. Such activities were also ascertained for other cytokines, such as il2 and il15, collectively indicating that, in contrast to the situation in mammals, T cell development in the thymus of teleosts is driven by a degenerate multi-component network of gc cytokines. This network configuration thus explains why deficiencies of single components have little detrimental effect. By contrast, the dependence on a single cytokine in the mammalian thymus has catastrophic consequences in case of congenital deficiencies in genes affecting the IL7 signaling pathway. We speculate that the transition from a degenerate to a non-redundant cytokine network supporting intrathymic T cell development emerged as the consequence of repurposing evolutionary ancient constitutive cytokine pathways for regulatory functions in the mammalian peripheral immune system.

RNA-seq analysis of neonatal mouse cochlear supporting cells [NonTreated_JM]

Project description:This study examined transcripts that are enriched in neonatal mouse cochlear supporting cells at postnatal day 1 and postnatal day 6. Supporting cells were purified by FACS sorting for GFP fluorescence from the cochleas of transgenic mice in which a BAC including the LFng locus drives the expression of GFP. Two replicates of GFP+ supporting cells were compared with all other cochlear cell types that were GFP-. We performed this experiment at two different ages, postnatal day 1 and postnatal day 6. mRNA profiles of supporting cells (GFP+) and all other cochlear cell types (GFP-), two replicates each, at P1 and P6 mice were generated by deep sequencing using Illumna TruSeq.

Notch Signaling Plays an Instructive Role in Supporting Cell Development and is Critical for Supporting Cell Survival

Project description:The sensory epithelium of the cochlea is a specialized structure responsible for the perception of sound. While much is understood about the development of the mechanosensory hair cells found within this epithelium, little is known about the development of the glial-like supporting cells. Here, we provide evidence that in addition to its well-characterized inhibitory function, canonical Notch signaling plays a positive, instructive role in the differentiation of supporting cells. Using γ-secretase inhibitor DAPT to acutely block canonical Notch signaling, we identified a cohort of Notch-regulated supporting cell-specific genes, with diverse functions in cell signaling, cell differentiation, neuronal innervation and synaptogenesis.

Gene Expression from hair cells and supporting cells in chick utricle

Project description:In adult mammals, hair cell loss is irreversible and may result in hearing and balance deficits. In contrast, birds can regenerate hair cells through differentiation of supporting cells and restore inner ear function, suggesting that hair cell progenitors are present in the population of supporting cells. We used microarrays to identify novel genes related to the regeneration in the chicken utricle. Supporting cell and hair cell populations of chicken utricle obtained by laser capture microdissection, following to do RNA extraction and hybridization on Affymetrix microarrays.

RNA-seq analysis of neonatal mouse cochlear supporting cells [Treated AK]

Project description:This study examined transcripts that are enriched in neonatal mouse cochlear supporting cells at postnatal day 1 and postnatal day 6 after inhibition of the Notch signaling pathway. Cochleas from postnatal day 0 and postnatal day 5 were cultured for 24 hours in the gamma secretase inhibitor DAPT or DMSO as a vehicle control. Supporting cells were purified by FACS sorting for GFP fluorescence from the cochleas of transgenic mice in which a BAC including the LFng locus drives the expression of GFP. Two replicates of GFP+ supporting cells were compared with all other cochlear cell types that were GFP-. We performed this experiment at two different ages, postnatal day 0+24 hours culture and postnatal day 5 + 24 hours culture. (corresponding to P1 and P6). mRNA profiles of P0 and P5 supporting cells (GFP+) and all other cochlear cell types (GFP-) treated with DAPT or DMSO, two replicates each, were generated by deep sequencing using Illumna TruSeq.
