Lutzomyia longipalpis saliva or salivary protein LJM19 protects against Leishmania braziliensis and the saliva of its vector, Lutzomyia intermedia. [PDF]

PLoS Neglected Tropical Diseases, 2011
BACKGROUND: Leishmania transmission occurs in the presence of insect saliva. Immunity to Phlebotomus papatasi or Lutzomyia longipalpis saliva or salivary components confers protection against an infection by Leishmania in the presence of the homologous ...

Lutzomyia longipalpis in Brazil: a complex or a single species? A mini-review [PDF]

Memórias do Instituto Oswaldo Cruz, 2007
Lutzomyia longipalpis is the main vector of Leishmania infantum chagasi, the causative agent of American visceral leishmaniasis (AVL). Although there is strong evidence that Lu. longipalpis is a species complex, not all data concerning populations from Brazil support this hypothesis.

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.

Expression, purification, crystallization and crystallographic study ofLutzomyia longipalpisLJL143 [PDF]

Acta Crystallographica Section F Structural Biology Communications, 2015
Leishmaniasis is a neglected vector-borne disease with a global prevalence of over 12 million cases and 59 000 annual deaths. Transmission of the parasite requires salivary proteins, including LJL143 from the New World sandflyLutzomyia longipalpis. LJL143 is a known marker of sandfly exposure in zoonotic hosts.

How Effective Are the Canine Visceral Leishmaniasis Vaccines Currently Being Tested in Dogs? A Systematic Review and Meta‐Analysis

Parasite Immunology, Volume 47, Issue 3, March 2025.
ABSTRACT Canine visceral leishmaniasis (CVL) is a zoonotic disease of great worldwide importance and can be prevented by vaccinating seronegative dogs. The objective of the present systematic review and meta‐analysis is to verify the efficacy rate of vaccines tested in dogs against CVL or L. infantum infection. We used PRISMA guidelines for this review
