Acute hypoglycemia attenuates serum matrix metalloproteinases and tissue inhibitors of metalloproteinases in type 2 diabetes
Authors' conclusion
Acute hypoglycemia induces subtype-specific, time-dependent MMP-TIMP shifts. T2D shows amplified, prolonged responses-especially MMP8, MMP3, and MMP9-with insufficient TIMP buffering, suggesting a proteolytic milieu that may impair ECM integrity and vascular stability.
Study context
- Population
- Adults with T2D and matched controls undergoing stepwise insulin to glucose ≤2.2 mmol/L
- Participants
- 46 adults
- Exposure
- T2D vs matched controls during insulin-induced hypoglycemia
- T2Dn = 23
- Controlsn = 23reference
- Outcome
- Circulating levels of eleven matrix metalloproteinases (MMPs) and three TIMPs
- Follow-up
- Baseline, during hypoglycemia, and up to 24 h post-recovery
Methodological detailsmatched controls
- Matched controls
Main finding
As reported in the abstract
MMP/TIMP responses to hypoglycemia · during hypoglycemia and up to 24 h post-recovery
- Controls: transient MMP1 rise during hypoglycemia with post-recovery decline
- T2D: MMP8 increased from 1-24 h and exceeded controls at 1-4 h
- T2D: MMP2 fell early then rebounded at 4 h
- MMP3 rose at 4 h in both groups and persisted to 24 h in T2D
- MMP9 remained elevated in T2D, decreasing only at 24 h
- TIMP3 declined during recovery in controls but stayed elevated in T2D; TIMP1/2 unchanged
Observational data: associations, not effects.
Further findings
Baseline MMP/TIMP levels
- T2D had higher MMP1, MMP7, MMP9, and TIMP1/3 than controls
