Relation Between LRG1 and CD4⁺ T Cells, Cognitive Impairment and Neurological Function in Patients with Acute Ischemic Stroke

Abstract

Objective:

To assess the relationship between LRG1 and CD4⁺ T cells, cognitive impairment and neurological function in acute ischemic stroke (AIS).

Methods:

Plasma LRG1 was detected by ELISA in 175 patients with AIS at baseline, day (D) 1, D7, month (M) 1 and M3.

Results:

LRG1 was negatively related to Th2 and Treg cells and positively linked to Th17 (all p < 0.05). LRG1 increased from baseline to D1, then decreased until M3 (p < 0.001). LRG1 at each assessment point was increased in patients with cognitive impairment or poor neurological function at M3 versus those without (all p < 0.05).

Conclusion:

LRG1 is linked to decreased Th2 and Tregs, increased Th17, cognitive impairment and nonideal neurological function recovery in patients with AIS.
