Golgi-Resident GTPase Rab30 Promotes the Biogenesis of Pathogen-Containing Autophagosomes.

Autophagy acts as a host-defense system against pathogenic microorganisms such as Group A Streptococcus (GAS). Autophagy is a membrane-mediated degradation system that is regulated by intracellular membrane trafficking regulators, including small GTPase Rab proteins. Here, we identified Rab30 as a novel regulator of GAS-containing autophagosome-like vacuoles (GcAVs).

Long-term outcome of non-surgical treatment in patients with oral leukoplakia.

Unlabelled: The standard treatments for oral leukoplakia range from careful observation to complete resection. No surgical intervention is chosen for several supposable reasons. Surgical treatment and no surgical treatment for oral leukoplakia have no defined basis for comparisons, and few studies have reported on the long-term outcomes of oral leukoplakia without surgery.

Rab17-mediated recycling endosomes contribute to autophagosome formation in response to Group A Streptococcus invasion.

Autophagy plays a crucial role in host defence by facilitating the degradation of invading bacteria such as Group A Streptococcus (GAS). GAS-containing autophagosome-like vacuoles (GcAVs) form when GAS-targeting autophagic membranes entrap invading bacteria. However, the membrane origin and the precise molecular mechanism that underlies GcAV formation remain unclear.
