AXL tyrosine kinase inhibition restores anti-PD-1 efficacy in melanoma through tumor-associated macrophage—dependent mechanisms 2255689
Immune checkpoint blockade (ICB) has transformed melanoma care, yet resistance is common and often driven by tumor-associated macrophages (TAMs). AXL, a Gas6-activated tyrosine kinase, is classically a tumor-intrinsic driver of invasion but is predominantly expressed by TAMs in melanoma, suggesting a role in regu...
