G Protein-Coupled Receptors and Second Messengers


When the ligand binds to its receptor, subsequent signaling mechanism must transfer the binding or occupation of receptor into transmembrane singling, which we call occupancy-response. Most transmembrane signaling is accomplished by a small number of different molecular mechanisms to transduce many different signals. These structures in the process of transmembrane signaling involve receptors on the cell […]

The topics of sites of infections and virulence are two fundamental content in the discipline of infectious diseases. As a pharmacist and clinician we have to read and understand them, which can direct our clinical practice at the right direction.

The course of any infectious disease can be divided into several distinguishable stages after the point when the potential pathogen enters the host. These stages are the incubation period, the prodromal stage, the acute stage, the convalescent stage, and the resolution stage. These stages are based on the progression and intensity of the host’s symptoms […]
