(40) mechanistically linked acute COVID-19 to diabetes and found that the SARS-CoV-2 receptor, ACE2, and related entry factors (TMPRSS2, Neuropilin 1, and Transferrin receptor) are expressed in beta cells, with selectively high expression of Neuropilin 1 (NRP1). Here, NRP1 is linked to diabetes mellitus.
