HIV-1 Long-Term non-progression: More Open Questions than Answers

The reason for long-term non-progression is one of the most elusive of all of the open questions in AIDS research. This review summarises the available epidemiological and viro-immunological data, paying particular attention to the recent advances in the genetic correlates of non-progression. Despite the large number of contributions in this field, the classification criteria remain heterogeneous, and may present substantial obstacles when interpreting the results of ongoing studies.
