Macrophages represent a fundamental component of the innate immune system that play a critical role in detecting and responding to pathogens as well as danger signals. Leishmania spp. infections lead to a notable alteration in macrophage metabolism, whereby infected cells display heightened energy metabolism that is linked to the integrity of host mitochondria.

Indigenous communities face not only the burden of these acute febrile illnesses, but also the cardiovascular complications that are worsened by urbanization. A cross-sectional study was conducted in an Indigenous population in the Northeast Region of Brazil to explore the association between arboviral infections (dengue, chikungunya, and Zika) and cardiac biomarkers, including cardiotrophin 1, growth differentiation factor 15, lactate dehydrogenase B, fatty-acid-binding protein 3, myoglobin, N-terminal pro-B-type natriuretic peptide, cardiac troponin I, big endothelin 1, and creatine kinase-MB, along with clinical and anthropometric factors.

The distribution of exposed strawberry plants in the area was based on a citizen science approach, where residents were invited to have the plants exposed outside their homes. Samples were collected from a total of 49 different locations, and their chemical composition was analyzed for 22 chemical elements using X-ray Fluorescence spectrometry.

Biotic stress was imposed on 6-month-old plants during five sampling intervals under greenhouse conditions. The and genes were upregulated for the Calcutta-4- and Krasan Saichon-resistant cultivars, and were validated in this study.
