The Immunology Podcast

Guest:

Dr. Ido Amit is a Principal Investigator and the Eden and Steven Romick Professorial Chair at the Weizmann Institute of Science. His lab is at the forefront of developing and applying cutting-edge single-cell genomics technologies alongside advanced computational approaches. By integrating these innovative tools in both animal models and human studies, his team uncovers the immune regulatory mechanisms and pathways that shape health and disease.

The Immunology Science Round Up

Modified RNA Prevents Autoimmunity – Researchers show that modified RNA from our own cells naturally blocks TLR7 and TLR8, preventing harmful immune activation.

Oncolytic Virus Boosts T Cells – In glioblastoma patients, a single virus treatment helped the immune system attack the tumor.

Rewiring the Immune System During Food Scarcity – When food is scarce, stress hormones rebalance the immune system to fight infection while conserving glucose and preserving immune memory.

Regulating Bystander T Cells – IL-4 can dial down how strongly memory CD8+ T cells respond to infection without direct antigen stimulation.

The Immunology Science Round Up

Immunosurveillance in the Skin: A neuro-epithelial axis can tune regional immunosurveillance against melanoma.

B Cells in Aging: B cells contributed to the age-related reduction of naive CD4 T cells.

The Gut–Brain Axis in Parkinson’s: Muscularis macrophages, housekeepers of intestinal homeostasis, modulate α-synuclein pathology and neurodegeneration in models of Parkinson’s disease.

How IL-2 Signaling Regulates Inflammation: IL-2 signaling promotes the generation of IL-10pos age-associated B cells, with implications for autoimmunity and inflammation.
