Improving melanoma treatment by blocking an enzyme

A new study found that blocking an enzyme called HPGDS may be a way to improve melanoma treatment for patients who don't respond to immunotherapy. The enzyme promotes tumor growth and metastasis dissemination by blocking T-cell activity, but blocking it boosts the immune response.
