Resumen La respuesta inflamatoria es un fenómeno inmunológico fundamental que se genera tras la infección o señales de daño en el organismo. En este proceso, participan activamente múltiples citocinas, moléculas que, por su pleiotropismo, no solo coordinan respuestas inmunitarias, sino que también regulan funciones neuronales cruciales que inciden...

Background: The endocannabinoid system (ECS) is active in brain regions involved in stress, food intake, and emotional regulation. The CB1 receptor and the fatty acid amide hydrolase (FAAH) enzyme regulate the ECS. Genetic variants in the FAAH gene (rs324420) and in the CNR1 gene (rs1049353) have been involved in both chronic stress and obesity. As...
