Physiological caffeine concentrations do not affect enteric neural crest cell migration in a mouse model

Olivier Romito, Justine Peres, Monica Dicu, Emeline Lelong, Isabelle Le Parco, Nadege Bondurand, Nicolas R Chevalier

This study shows that physiological caffeine doses do not impair enteric neural crest cell migration in a mouse model, suggesting caffeine is not directly responsible for Hirschsprung disease risk.

Mechanisms determining Schistosoma mansoni CRAC channel activation

Ana Eliza Zeraik, Olivier Romito, Aparna Gudlur, Kenneth A. Stauderman, Gönül Veliçelebi, Ana Paula Ulian de Araújo, Mohamed Trebak, Zachary Katz

This study investigates calcium signaling in Schistosoma mansoni by analyzing STIM and ORAI proteins, identifying pharmacological differences that could enable selective targeting of schistosome calcium channels.

Endothelial CYB5R3 couples store-operated calcium entry to TRPV2 activation and vascular fitness

Máté Katona, Shuai Yuan, Robert Hall, Olivier Romito, Stefanie N. Taiclet, Sydney S. Tomman, Scott A. Hahn, Katherine C. Wood, Mohamed Trebak, Adam C. Straub

This paper identifies CYB5R3 as a redox switch that couples store-operated calcium entry to TRPV2 activation, enhancing vascular function through NO-dependent oxidative inhibition of PTPN1.
