Summary

In this first lecture of the 2025-2026 series, Professor Sonia Garel introduces the framework of neuroimmune interactions, focusing on how immune signals influence behavior and social interactions. She recaps previous work on the communication pathways between the nervous and immune systems, including humoral and neural routes, and the concept of immunoception. The lecture then delves into recent studies, primarily in animal models, showing that cytokines such as IL-17 can act on specific brain nuclei to modulate anxiety and social behaviors, including social withdrawal during inflammation. Garel emphasizes the causal evidence from animal studies and discusses the implications for understanding the physiological role of immune signals in shaping behavior. She outlines the course structure, covering pathological disruptions in the next lecture, and later topics on pain and sleep. The lecture is part of the Collège de France’s mission to disseminate cutting-edge research.
