Figure 1. Monocyte related cells create “cell based metabolic barriers” (CBMB) to glucose and oxygen diffusion at sites of glucose sensor implantation and compromise CGM.
Based on the literature and recent data from our laboratories, we hypothesized that the recruitment and accumulation of monocyte related cells (i.e. MQ and FBGC) at the sensor-tissue interface create a “Cell Based Metabolic Barrier” (white arrow) to glucose and oxygen that is diffusing from the vasculature (V) toward implanted glucose sensors (sensor).
