The pathogenesis of<i>Leishmania</i>/HIV co-infection: cellular and immunological mechanisms
Bibliographic record
Abstract
The intracellular protozoan parasites of the genus Leishmania have been recognized as opportunistic pathogens in immunosuppressed individuals, including those infected with human immunodeficiency virus type-1 (HIV-1). Leishmaniasis and AIDS overlap in several sub-tropical and tropical regions around the world, including the Mediterranean area. In 1994, 3%-7% of HIV-1-infected individuals in southern Europe developed visceral leishmaniasis. In humans, interestingly, both HIV-1 and Leishmania interact with, invade, and multiply within cells of myeloid or lymphoid origin. The combined modulation of Leishmania - and HIV-1-related pathogenesis in the co-infected cases is therefore probably a realistic goal. In the light of the recent demonstration that L. donovani can up-regulate HIV-1 replication, both in monocytoid and lymphoid cells in vitro and in co-infected individuals, it is clear from the epidemiological data available that Leishmania can probably act as a powerful co-factor in the pathogenesis of HIV-1 infection. In those who are co-infected, complex mechanisms involving cytokine secretion and cellular-signalling events play pivotal roles in the Leishmania-mediated activation and pathogenesis of HIV-1. An overview of the recent findings concerning this Leishmania/HIV-1 interaction is presented here.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
