DC-SIGN receptor is expressed by cells from cutaneous leishmaniasis lesions and differentially binds to Leishmania (Viannia) braziliensis and L. (Leishmania) amazonensis promastigotes.

Background: Dendritic cells (DCs) specific intercellular adhesion molecule (ICAM)-3-grabbing non integrin receptor (DC-SIGN) binds to subgenera Leishmania promastigotes mediating its interaction with DC and neutrophils, potentially influencing the infection outcome.

Objectives: In this work, we investigated whether DC-SIGN receptor is expressed in cells from cutaneous leishmaniasis (CL) lesions as well as the in vitro binding pattern of Leishmania (Viannia) braziliensis (Lb) and L. (L.

Dual Role of Insulin-Like Growth Factor (IGF)-I in American Tegumentary Leishmaniasis.

Background: Cytokines and growth factors involved in the tissue inflammatory process influence the outcome of infection. Insulin-like growth factor (IGF-I) constitutively present in the skin may participate in the inflammatory process and parasite-host interaction. Previous work has shown that preincubation of () with recombinant IGF-I induces accelerated lesion development.

Leishmania (V.) braziliensis infection promotes macrophage autophagy by a LC3B-dependent and BECLIN1-independent mechanism.

Leishmania (Viannia) braziliensis is one of the main etiological agents of tegumentary leishmaniasis in Latin America. The establishment of a successful infection in host cells requires several key events including phagocytosis, phagolysosomal maturation impairment, and parasite replication. Autophagy is accountable for the physiological turnover of cellular organelles, degradation of macromolecular structures, and pathogen elimination.

Chagas disease in Virgem da Lapa, Minas Gerais, Brazil: left ventricle aneurysm and the risk of death in the 24-year interval.

Background: Left ventricular aneurysm (LVA) is indicator of high morbidity in Chagas' disease. A cross-sectional study performed identified LVA in 18.8% of the chronic chagasic patients (CCP).

An open toolkit for tracking open science partnership implementation and impact.

Serious concerns about the way research is organized collectively are increasingly being raised. They include the escalating costs of research and lower research productivity, low public trust in researchers to report the truth, lack of diversity, poor community engagement, ethical concerns over research practices, and irreproducibility. Open science (OS) collaborations comprise of a set of practices including open access publication, open data sharing and the absence of restrictive intellectual property rights with which institutions, firms, governments and communities are experimenting in order to overcome these concerns.
