Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer

Immunology, Volume 178, Issue 3, Page 377-386, July 2026.
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

An Unusual Presentation of Cutaneous Leishmaniasis in a Patient with Substance Use: A Diagnostic and Management Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT In patients with atypical ulcers and travel history to endemic areas, a comprehensive diagnostic workup for cutaneous leishmaniasis is imperative. This case confirms Leishmania tropica through combined microscopy, culture, and PCR, leading to successful treatment with systemic glucantime and adjunctive wound care.
