Individuals living in regions where malaria is endemic develop an acquired immunity to malaria which enables them to remain asymptomatic while still carrying parasites. Field studies indicate that cumulative exposure to a variety of diverse Plasmodium parasites is required for the transition from symptomatic to asymptomatic malaria. This study used a simulation model of the within-host dynamics...
Inflammasomes are cytosolic multiprotein complexes that sense microbial motifs or cellular stress and stimulate caspase-1-dependent cytokine secretion and cell death. Recently, it has become increasingly evident that both DNA and RNA viruses activate inflammasomes, which control innate and adaptive immune responses against viral infections. In addition, recent studies suggest that certain micro...
Many athletes believe that physical training enhances immunity and helps prevent upper respiratory tract infection (URTI) like the common cold or “flu” (influenza). They also believe that physical activity and fitness help them overcome any minor infections they do get. On the other hand, based largely on anecdotes and on popularization of a link between physical or psychological stress and “im...
Viral infections in animal models appear to be ideal systems for determining toxicity to the immune system by environmental substances. Since many viral infections that are utilized in animals produce systemic disease, these models provide an opportunity to evaluate the interaction between virus and components of host resistance. In these infections it is possible to delineate the role of antib...
