During my PhD thesis I want to investigate selection pressures for trans-generational immune priming and evaluate the incorporated costs and benefits. I will evaluate the effects of trans-generational immune priming on life-history parameters as immune priming is expected to be energetically costly for both parents and offspring. I further want to explore which mechanisms determine trans-generational immune priming in the sex-role reversed pipefish Syngnathus typhle. This will be done by identifying the identity of transferred immune compounds and by discovering the role of epigenetic factors that result in a significant higher immune response after parental pathogen exposure. We hypothesize that (i) antibodies are transmitted to the offspring not only by females during oogenesis but also by males over the placenta-like structure and that (ii) epigenetic factors such as differential DNA-methylation pattern influence the gene expression of immune genes in juveniles.
