Implication of extracellular matrix related molecules in the immune response and spermatogenesis in the teleost fish gilthead seabream / Regulación de la espermatogénesis y respuesta inmunitaria por moléculas de la matriz extracelular en peces teleósteos (original) (raw)

ABSTRACT This work studies the extracellular matrix (ECM) environment and their implications in the immune response and spermatogenesis in gilthead seabream. This is a useful model to study interactions between immune and reproductive systems, considering its biological characteristics, such as seasonal breeding, testicular involution and sexual reversion. The results showed collagen and its derived peptides as able to act as damage signals (DAMPs), modulating in a specific form the innate immune response and the early inflammation processes in seabream professional phagocytes and fibroblasts. In addition, the strong correlations between ECM related molecules, under physiological conditions and during development, are modulated as part of the response against DAMPs and pathogen derived molecules. Finally, we found that in addition to the integrin beta 1a (ITGB1a) which is constitutively expressed, in seabream there is an ITGB1b which is mainly expressed in testis and during spermato...
