CALR and neoplasm: These dying tumor cells could release damage‐associated molecular patterns (DAMPs), such as calreticulin (CRT), which could act as an “eat me” signal to stimulate the antigen presenting function of dendritic cells (DCs).[11, 12, 13, 14] Currently, researches have mostly focused on adjusting the light absorption of phototherapy agents to the near infrared (NIR) region to enhance the tissue penetration and trigger prominent ICD.
