Development of Leishmania mexicana in Lutzomyia longipalpis in the absence of sugar feeding [PDF]

Memórias do Instituto Oswaldo Cruz, 2019
The leishmaniases are caused by Leishmania parasites and transmitted through the bites of phlebotomine sand flies. During parasite development inside the vector's midgut, promastigotes move towards the stomodeal valve, a mechanism that is crucial for transmission.

Neuroimmune Pain and Its Manipulation by Pathogens

Evolutionary Applications, Volume 18, Issue 4, April 2025.
ABSTRACT Recent studies highlight extensive crosstalk that exists between sensory neurons responsible for pain and the immune system. Cutaneous pain neurons detect harmful microbes, recruit immune cells, and produce anticipatory immunity in nearby tissues. These complementary systems generally protect hosts from infections.
