Surface protein precursors traffic to lipoteichoic acid-rich septal membranes of Staphylococcus aureus for cleavage of their YSIRK-GXXS motif signal peptides and SecA-mediated translocation across the plasma membrane.
A fluoroquinolone resistant variant of Salmonella Typhi has emerged that is likely to be widespread in the Indian subcontinent; therefore fluoroquinolones should not be recommended for empirical typhoid fever therapy in this setting.
Somatostatin-expressing interneurons of the rodent dentate gyrus fall into at least two functionally distinct interneuron types with different synaptic integrations into the local dentate gyrus and the more distant medial septum neuronal network.
Discovering that Hoxb1 acts as a repressor of cardiac differentiation on second heart field progenitor cells helps us to understand the etiology of congenital heart defects such as atrioventricular septal defects.
In the injured sciatic nerve, blood-derived monocytes and macrophages eat dying leukocytes, thereby contributing to nerve debridement and inflammation resolution, and this correlates with neuronal regeneration.
