Elevated T Cell Immunoreceptor with Ig and ITIM Domains (TIGIT) Expression and Immune Cell Dysfunction Characterize Complex Proteins Associated With SET1 (COMPASS)–Like Complex Gene–Mutated Pancreatic Ductal Adenocarcinoma (PDAC)

Key Points

• Elevated TIGIT expression correlates with immune cell dysfunction in pancreatic ductal adenocarcinoma.
• Overall, immune cell dysfunction was observed in a significant number of cases with SET1-like complex gene mutations.
• Observational analysis of pancreatic ductal adenocarcinoma patients identified key genetic mutations affecting immune response.
• Findings highlight the need for targeted therapies to overcome immune evasion in this cancer type.
