Type 2 & other diabetes

Low levels of soluble neuropilin‐1 were associated with depression in adults with newly diagnosed type 2 diabetes

Diabetes Obes MetabPublished Cross-sectional study

Authors' conclusion

Low sNRP-1 (<226 ng/mL) was associated with depression in all patients with newly diagnosed T2D. In younger patients (<60 years), depression, pre-existing myocardial infarction and younger age were associated with low sNRP-1. In older patients, only depression and younger age were associated with low sNRP-1.
