View SamplesSpermatogenesis is a complex differentiation process that involves the successive and simultaneous execution of three different gene expression programs: mitotic proliferation of spermatogonia, meiosis, and spermiogenesis. Testicular cell heterogeneity has hindered its molecular analyses. Moreover, the characterization of short, poorly represented cell stages such as initial meiotic prophase ones (leptotene and zygotene) has remained elusive, despite their crucial importance for understanding the fundamentals of meiosis.We have developed a flow cytometry-based approach for obtaining highly pure stage-specific spermatogenic cell populations, including early meiotic prophase. Here we combined this methodology with next generation sequencing, which enabled the analysis of meiotic and postmeiotic gene expression signatures in mouse with unprecedented reliability. Interestingly, we found that a considerable number of genes involved in early as well as late meiotic processes are already on at early meiotic prophase, with a high proportion of them being expressed only for the short time lapse of lepto-zygotene stages. Besides, we observed a massive change in gene expressionpatterns during medium meiotic prophase (pachytene) when mostly genes related to spermiogenesis and sperm function are already turned on. This indicates that the transcriptional switch from meiosis to post-meiosis takes place very early, during meiotic prophase, thus disclosing a higher incidence of post-transcriptional regulationin spermatogenesis than previously reported. Moreover, we found that a good proportion of the differential gene expression in spermiogenesis corresponds to up-regulation of genes whose expression starts earlier, at pachytene stage; this includes transition protein- and protamine-coding genes, which have long been claimed to switch on during spermiogenesis. In addition, our results afford new insights concerning X chromosome meiotic inactivation and reactivation. This work provides for the first time an overview of the time course for the massive onset and turning off of the meiotic and spermiogenic genetic programs. Importantly, our data represent a highly reliable information set about gene expression in pure testicular cell populations including early meiotic prophase, for further data mining towards the elucidation of the molecular bases of male reproduction in mammals.

View SamplesIn the terms of vaccine efficacy and duration of protection in malaria vaccination is major concern against malaria. On the other hand, it is facing complications in development and administration to the host. However, whole sporozoites vaccination (WSV) is far more efficacious than any other alternative strategy. We have found that the intermittent sporozoite challenge to immune mice following RAS vaccination extends the longevity of sterile protection by maintaining CD8+T cell memory responses to LS infection and also helps in CD8a+DCs accumulation and activation in liver. Consequently, there has been great interest in elucidating and understating the sterile immunological response at mechanistic level. The information we have generated can then potentially be used in generation of next generation vaccine with improved efficacy and duration of protection. In this work, to elucidate the host initial immune response underlying the protective effects of a WSV in shaping the protected sterile protection and advances its immunogenicity in the future, a high-throughput RNA sequencing technology was used to investigate the immunization related gene expression patterns of mouse immunized with radiation attenuated sporozoites (RAS) vaccine.
