Interplay between the environment and the immune system

Resumen

About IMMUNOPERU 2025: This IUIS-ALACI-PSI course has brought together a diverse group of students, immunologists and experts to share their distinct perspectives, skills and expertise. The focus was on a variety of endemic and emerging diseases related to environmental and climate change. The goal was to catalyze the development of novel concepts, methods and approaches in addressing these emerging challenges. MAIN TOPICS: The course has addressed the Impact of environmental exposures on immunity in infectious disease, chronic inflammation and cancer with particular attention to: Changes in microbial communities and their metabolites that drive inflammatory disease (eg. effects of antibiotics, dietary and other factors) Environmental cues and pollutants linked to the development of hematologic malignancies. The impact of climate change on endemic infectious diseases (eg. Tuberculosis, Dengue Fever, Chagas Disease, and others). ABSTRACTS: 1.
