ALB and neoplasm: Since endogenous albumins circulate in the lymphatic system, antigens can be transported to the lymph nodes getting a ride of albumin train if they are able to bind to endogenous albumins.110,111 Currently, we know that albumin is a transporter protein for fatty acid molecules, which can capture and bind some lipid molecules.112 Using this mechanism, the researchers designed a tumor peptide vaccine with lipophilic tails.
