In this study, we examined the GnIH and GnIH receptors (GnIHRs) expression from embryogenesis to adult stage and tissue-specific expression in adult Catla catla using quantitative real-time (qRT) PCR. The qRT PCR analysis of GnIH mRNA during ontogenetic development showed the increasing trend from early developmental stages to the adult stage with the highest expression in 24 months fish. However, the expression of two GnIH receptors, GnIHR1 and GnIHR2 also increased from larval stages to the adults with a peak at 17 days post-hatching, while GnIHR3 showed the higher mRNA expression during embryogenesis and then decreasing gradually. Tissue distribution analysis of GnIH showed the highest mRNA expression of GnIH in the brain, followed by gonads of both the sexes. GnIHR1 and GnIHR2 were also highly expressed in the brain and gonads of both the sexes, while GnIHR3 showed the highest expression in gonads of both the sexes without any expression in the brain. These results suggest that the brain is the primary site of action for GnIH, GnIHR1 and GnIHR2, while gonads for GnIHR3.Helicobacter pylori (Hp) is a likely trigger of systemic sclerosis (SSc), but systemic antigen-specific antibody (Ab) responses in a well-defined cohort of SSc patients have not been thoroughly assessed. Line immunoassay and immunoblotting testing Abs against 15 Hp antigens were performed in 91 SSc patients and 59 demographically matched healthy controls (HCs). Results were validated in an independent cohort of 35 SSc patients. Anti-Hp positivity was detected in 67% SSc patients vs 76.3% HCs. Among anti-Hp (+) individuals, anti-p67-FSH was less frequent in SSc than HCs (p = 0.016), whereas reactivity to the remai
