by Gertrud U. Rey According to established scientific dogma, infection of cells with HIV-1 leads to delivery of the viral capsid into the cell cytoplasm, followed by “uncoating” of the capsid to release the single-stranded RNA genome. A viral-encoded enzyme called reverse transcriptase then catalyzes the conversion of the viral RNA into a single strand …

These adaptive immunity elements coordinate over time to develop a response that protects from re-infection and disease upon a second exposure to the same pathogen. The second exposure will immediately lead to …
by Gertrud U. Rey Satellite viruses lack one or more of the elements needed to replicate, and thus they depend on co-infection with a helper virus that can provide the missing components. In a well-known example of a satellite-helper system, Hepatitis D virus requires the presence of its helper Hepatitis B virus to make copies …
