Comparative proteomic analysis of kinesin-8B deficient Plasmodium berghei during gametogenesis.

Plasmodium blood stages, responsible for human to vector transmission, termed gametocytes, are the precursor cells that develop into gametes in the mosquito. Male gametogenesis works as a bottleneck for the parasite life cycle, where, during a peculiar and rapid exflagellation, a male gametocyte produces 8 intracellular axonemes that generate by budding 8 motile gametes. Understanding the molecular mechanisms of gametogenesis is key to design strategies for controlling malaria transmission.

Proteomic profile of pre-implantational ovine embryos produced in vivo.

The present study was conducted to decipher the proteome of in vivo-produced pre-implantation ovine embryos.

Six days later, 54 embryos (morula and blastocyst developmental state) were recovered from eight ewes and pooled to obtain sufficient protein for proteomic analysis.

IL-4 absence triggers distinct pathways in apical periodontitis development.

Dental pulp is a specialized tissue able to respond to infectious processes. Nevertheless, infection progress and root canal colonization trigger an immune-inflammatory response in tooth-surrounding tissues, leading to apical periodontitis and bone tissue destruction, further contributing to tooth loss. In order to shed some light on the effects of IL-4 on periradicular pathology development modulation, microtomographic, histological and proteomic analyses were performed using 60 mice, 30 wild type and 30 IL-4/.
