Microbiota-driven stem-like lymphoid niche with CD70+ ILC2s sustains progenitor exhausted T cells, redefining TLS-associated antitumor immunity.
- Why it matters: Understanding the heterogeneity of tertiary lymphoid structures (TLSs) is crucial because their varied functions can lead to different clinical outcomes in immunotherapy. Clarifying the mechanisms behind TLS organization may improve therapeutic strategies.
- What they did: Hu et al. examined the role of microbiota in TLSs and identified a niche where CD70+ ILC2s support progenitor exhausted T cells, revealing a microbiota-orchestrated cellular organization.
- The result: This discovery suggests that microbiota influence TLS function by maintaining a stem-like lymphoid niche, which could impact the effectiveness of immunotherapies targeting TLSs.
