by Gertrud U. Rey Some viruses have a lipid envelope surrounding their protein capsid, which they get from the host cell membrane during the budding process. The envelope acts as an anchor for viral glycoproteins, which facilitate entry of the newly budded virus into a new cell by recognizing and binding host cell receptors. Such …

Shortly after Félix d€™Herelle discovered viruses that infect bacteria in 1917 (also found in 1915 by Twort), he recognized their therapeutic potential for treating infections. The discovery of penicillin in 1928 began the golden age of antibiotics, which pushed aside progress in treating infections with bacteriophages. With the advent of widespread antimicrobial resistance, development of …
Retroviruses have been infecting vertebrates for over 450 million years. Because retroviral DNA integrates into host cell DNA, the vertebrate genome is littered with remnants of these infections. Some of this retroviral DNA has been co-opted by the cell for a variety of beneficial purposes, such as development of the placenta and the control of …
