mRNA vaccines as unplanned immunotherapy primers ⚡ SARS-CoV-2 mRNA vaccination triggers a type I IFN surge, activates APCs, and primes CD8⁺ T cells for tumor antigen recognition. 🧩 IFN-driven PD-L1 upregulation 🧭 Enhanced T-cell infiltration into “cold” tumors 🌐

ADCs biology is shaped by antibody, linker stability, payload, & immune synergy 🌊 Systemic kinetics: DAR balance critical; high DAR → higher clearance/toxicity, low DAR → weak efficacy 🔀 Linker chemistry controls payload release: cleavable vs non-cleavable,

ADCs are not just “guided missiles” — new biology is reshaping how we view them 🌊 Continuous payload exposure in circulation sustains cytotoxic thresholds 🔀 Antigen level ≠ response: extracellular cleavage enables efficacy in “HER2-null” tumors 🛡️ Fc functions &

Mismatch Repair Deficiency: From DNA repair failure to immunotherapy sensitivity 🌊 Loss of MMR → microsatellite instability → hypermutation → abundant neoantigens 🛡️ Immune context: TIL-rich & inflamed, but immune checkpoints (PD-1, CTLA4, LAG3) and fibrotic stroma

Circulating Tumor Cells: Mechanistic drivers of metastasis & biomarker promise 🌊 Intravasation via EMT/VEGF; clusters = 25–50× ↑ metastasis 🔀 Lineage plasticity (epithelial ↔ mesenchymal ↔ neuroendocrine) 🛡️ Platelets & neutrophils shield CTCs; PD-L1+ escape 🧬

Cancer cachexia = an underdiagnosed, lethal syndrome. · Affects up to 80% in pancreatic CA, 40% in lung. · It’s not just weight loss—think systemic inflammation, altered metabolism, fat/muscle wasting. · GDF-15, IL-6, activin A are key molecular drivers. · A major unmet need in

Humoral Immunity in CheckPoint Inhibitors Response CPI response isn't just T cell-driven. In a 374-patient CPI cohort, @Nature study shows: ✅ Broad, stable anti-exoproteome autoantibody signatures ✅Some AAbs enhance CPI efficacy (e.g., by blocking IL-6, IFN-I, TL1A) ✅Others
