B7-H4 Expression in Human Melanoma: Its Association with Patients' Survival and Antitumor Immune Response

Abstract
Purpose: Cancers have developed a number of strategies to escape immune responses including the differential expression of costimulatory molecules of the B7 family. B7-H3 and B7-H4 have recently been described in different tumor entities but the relevance for melanoma has not yet been studied so far.
