β-Glucan-Induced Trained Immunity Protects against Leishmania braziliensis Infection: a Crucial Role for IL-32

Cell Reports, 2019
Summary: American tegumentary leishmaniasis is a vector-borne parasitic disease caused by Leishmania protozoans. Innate immune cells undergo long-term functional reprogramming in response to infection or Bacillus Calmette-Guérin (BCG) vaccination via a ...

The TLR2/6 ligand PAM2CSK4 is a Th2 polarizing adjuvant in Leishmania major and Brugia malayi murine vaccine models. [PDF]

, 2016
Toll-like receptors (TLRs) play an important role in the innate and adaptive immune responses to pathogens, and are the target of new vaccine adjuvants.

Infection of Human Monocytes with Leishmania infantum Strains Induces a Downmodulated Response when Compared with Infection with Leishmania braziliensis

Frontiers in Immunology, 2018
Human infection with different species of Leishmania leads to distinct clinical manifestations, ranging from relatively mild cutaneous (Leishmania braziliensis) to severe visceral (Leishmania infantum) forms of leishmaniasis.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Immunoactivation and immunopathogeny during active visceral leishmaniasis Imunoativação e imunopatogenia durante leishmaniose visceral ativa

Revista do Instituto de Medicina Tropical de São Paulo, 2009
Visceral leishmaniasis is caused by protozoan parasites of the Leishmania donovani complex. During active disease in humans, high levels of IFN-γ and TNF-α detected in blood serum, and high expression of IFN-γ mRNA in samples of the ...

Anti-Leishmania IgG is a marker of disseminated leishmaniasis caused by Leishmania braziliensis

International Journal of Infectious Diseases, 2021
Background: In this study, we determined the accuracy of anti-Leishmania IgG and IgG subclasses to distinguish clinical forms of American tegumentary leishmaniasis (ATL) and and determined the relationship between antibodies levels with cytokine ...

Interleukin-12 p40 secretion by cutaneous CD11c(+) and F4/80(+) cells is a major feature of the innate immune response in mice that develop Th1-mediated protective immunity to Schistosoma mansoni [PDF]

, 2003
Radiation-attenuated (RA) schistosome larvae are potent stimulators of innate immune responses at the skin site of exposure (pinna) that are likely to be important factors in the development of Th1-mediated protective immunity.

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

Evaluation of the Cutaneous Immunological Milieu Before and After Treatment With Meglumine Antimoniate in Dogs Naturally Affected by Leishmaniosis due to Leishmania infantum

Veterinary Dermatology, EarlyView.
Background: Canine leishmaniosis (CanL) is a zoonotic disease of variable severity. The typical immune response is driven by an exaggerated humoral immune response. Protective immunity is mediated by pro‐inflammatory cytokines that enhance macrophage leishmanicidal activity. Objective: To evaluate the cutaneous and the systemic immune responses as well
