New immunotherapy strategy targets macrophage receptors to enhance melanoma treatment

Researchers from Moffitt Cancer Center have found a new way to boost cancer immunotherapy by targeting a protein called macrophage receptor with collagenous structure, or MARCO. Their study, published in the Journal for ImmunoTherapy of Cancer, shows that blocking MARCO in combination with a type of immunotherapy known as anti-CTLA4 therapy, significantly enhances tumor regression in melanoma, the deadliest form of skin cancer.
