The porcine granulocyte proteome: expression changes in a transgenic pig model for diabetes

As transgenic INSC94Y-pigs develop a stable diabetic phenotype we were able to study the influence of elevated blood glucose levels on primary immune cells in vivo. We investigated the neutrophil proteome and compared data of transgenic animals to a control group. A total of 2371 proteins describing the whole neutrophil proteome were identified, including 396 proteins (17% of proteome) newly associated to expression in porcine neutrophils. Our studies provide novel information on the porcine granulocyte proteome and contribute to a better understanding of molecular mechanisms involved in altered immune cell function in diabetes. The data presented here is highly relevant for veterinary medicine and has translational quality for diabetes in human.
