Desensitization to Filgrastim in a 2-Year-Old Girl With a Vaginal Endodermal Sinus Tumor

This article describes a protocol for creating a microfluidic vagina-on-a-chip (Vagina Chip) culture device that enables the study of human host interactions with a living vaginal microbiome under microaerophilic conditions. This chip can be used as a tool to investigate vaginal diseases as well as to develop and test potential therapeutic...

The purpose of this protocol is to imitate human group B Streptococcus (GBS) vaginal colonization in a murine model. This method may be used to investigate host immune responses and bacterial factors contributing to GBS vaginal persistence, as well as to test therapeutic...

G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...
