Lactate Accelerates Early Angiogenesis and Bone Regeneration Through Macrophage M1 Polarisation

Cell Proliferation, EarlyView.
During the early stage of bone defect healing, lactate accumulates and contributes to increasing NOD1 expression by stabilising HIF1α that in turn triggers a calcium influx, which ultimately polarises macrophages towards the M1 phenotype and accelerates vascularisation of endothelial cells.

Erythrocyte deformability correlates with microvascular ischemia and disease severity in diabetic retinopathy

Journal of Diabetes Investigation, EarlyView.
Under physiological conditions, deformable erythrocytes pass smoothly through the capillary network, maintaining retinal capillary perfusion (A). In pathological conditions, reduced erythrocyte deformability causes irregular passage and stagnation within capillaries, resulting in localized blood flow stasis and microvascular congestion, leading to ...
