Researchers identify a new HIV reservoir

HIV cure research to date has focused on clearing the virus from T cells, a type of white blood cell that is an essential part of the immune system. Yet investigators in the Division of Infectious Diseases at the University ...

HIV expert's studies yielding insights into diseases of aging

While AIDS originally was seen as an adaptive immune disease, the research of Alan Landay, PhD, has contributed to a view of it as a cell driven-inflammation linked to immunosenescence—the gradual deterioration of the immune ...

Videos reveal how HIV spreads in real time

How retroviruses like HIV spread in their hosts had been unknown—until a Yale team devised a way to watch it actually happen in a living organism. The elaborate and sometimes surprising steps the virus takes to reach and ...

Pathogenesis

The pathogenesis of a disease is the mechanism by which the disease is caused. The term can also be used to describe the origin and development of the disease and whether it is acute, chronic or recurrent. The word comes from the Greek pathos, "disease", and genesis, "creation".

Types of pathogenesis include microbial infection, inflammation, malignancy and tissue breakdown.

Most diseases are caused by multiple pathogenetical processes together. For example, certain cancers arise from dysfunction of the immune system (skin tumors and lymphoma after a renal transplant, which requires immunosuppression).

Often, a potential etiology is identified by epidemiological observations before a pathological link can be drawn between the cause and the disease.
