Virus infections initiate when virions bind to receptors on the cell surface. It is well known that cells can be made susceptible to infection by providing DNA encoding the virus receptor. For example, mice cannot be infected with poliovirus, but become susceptible if they are given the human poliovirus receptor gene. Now we have learned that providing the receptor protein …

Vincent Racaniello interviews Harmit Malik, PhD, Fred Hutchinson Cancer Research Center. Harmit and his laboratory are interested in a variety of problems that are characterized by evolutionary conflict. This video is one of 26 video interviews with eminent virologists that are part of the supplemental material for Principles of Virology, 4th Edition, published by ASM Press. …
A new breed of vaccines is on the horizon: they replicate in one type of cell, allowing for their production, but will not replicate in humans. Two different examples have recently been described for influenza and chikungunya viruses. The influenza virus vaccine is produced by introducing multiple amber (UAG) translation stop codons in multiple viral genes. …
Virophages (the name means virus eater) were first discovered to replicate only in amoeba infected with the giant mimiviruses or mamaviruses. They reduce yields of the giant viruses, and also decrease killing of the host cell. Another virophage called mavirus has been found to integrate into the genome of its host and behaves like an inducible antiviral defense system …
By David Tuller, DrPH David Tuller is academic coordinator of the concurrent masters degree program in public health and journalism at the University of California, Berkeley. The past year has been a disaster for proponents of the PACE trial. They have faced growing international resistance to their exaggerated claims that cognitive behavior therapy and graded …

The popular history of HIV/AIDS describes a man known as Patient Zero, a sexually active flight attendant who traveled the globe and initiated the AIDS epidemic in North America. A new analysis of the viral genome recovered from his serum and that of other patients in the 1970s proves beyond a doubt that he was …
