Novel diagnostic screens type 1 diabetes (IDDM)

摘要

The present invention features methods for diagnosing insulin-dependent diabetes mellitus (IDDM) in a test subject, for example a subject at risk of developing IDDM, which involve detecting hyper-responsive Ca2+ mobilization in cells obtained from the test subject. Hyper-responsive Ca2+ mobilization can be detected in cells contacted with a stimulatory agent, preferably in cells contacted with a potentiating agent and a stimulatory agent. Methods of the present invention include comparing Ca2+ mobilization in cells from the test subject to Ca2+ mobilization in cells from a control subject. The present invention further features kits for use in the detection of IDDM.
