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 ...

Sponges survive and develop infaunal snapping shrimp communities when transplanted immediately after clonal propagation: implications for restoration

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Sponges historically dominated the heterotrophic biomass of Florida Bay's hard‐bottom habitat, providing crucial ecosystem services including shelter for soniferous shrimp that contribute to the marine soundscape. The loss of the sponge communities has inspired restoration efforts using in‐water nurseries for vegetative ...

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

Ecography, Volume 2026, Issue 6, June 2026.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

Cocirculation of 2 Genotypes of Toscana Virus, Southeastern France

Emerging Infectious Diseases, 2007
Toscana virus (TOSV), an arthropodborne phlebovirus transmitted by sandflies, can cause febrile illness and meningitis. The vector of TOSV in France was unknown. We detected TOSV RNA in 2 (female Phlebotomus perniciosus) of 61 pools of sandflies captured

Sandfly surveillance and investigation of Leishmania spp. DNA in sandflies in Kosovo

Medical and Veterinary Entomology, 2020
Abstract In the past decade, leishmaniasis seems to be re‐emerging in Balkan countries. There are serious implications that Kosovo is a visceral leishmaniasis endemic region with autochthonous transmission; nevertheless, surveillance of vectors, reservoirs or the disease is not yet established.

Outbreak of Toxoplasmosis Caused by the Brazilian Lineage Type BrII in Black Lion Tamarins (Leontopithecus chrysopygus) Co‐Infected With Leishmania sp.

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Toxoplasmosis and leishmaniosis are zoonotic diseases that affect several species of neotropical primates. Methods Three black lion tamarins (Leontopithecus chrysopygus) kept at a Brazilian zoo died due to a superacute disease.

Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 246-259, June 2026.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

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 ...
