Mechanistic study identifying exosome trafficking as a regulator of adipocyte thermogenesis in cell and mouse models, without clinical outcomes or human efficacy data to support therapeutic application.
Mechanistic study in vitro and from sequencing datasets showing bacterial modulation of MR1 expression and MAIT activation, raising a question about whether this influences checkpoint blockade response rather than demonstrating a clinical effect.
Mechanistic discovery in preclinical models with supporting human correlative data, but lacks clinical trial evidence of efficacy in patients with immunotherapy resistance.
Mechanistic cell-based study establishing a signaling principle in cancer cells; proposes a model for RTK fusion behavior but lacks clinical outcome data or in vivo validation needed to guide practice.
