Abstract

Objective: In order to study the diagnosis and treatment value of chelating anti-IL-1β mAb-SPIONs in temporal lobe epilepsy model induced by lithium chlorid and pilocarpine. Methods: Forty-five temporal lobe epilepsy model rats were randomly and equally divided into saline group, plain-SPIONs group, anti-IL-1β mAb-SPIONs group. Each group was injected with equal particles at day 3 and day 14 after the onset of seizures. MRI were conducteds before and 4 hours after particles injection and T2 values were measured. The distribution of iron particles in the epileptic tissue was observed and the neuronal loss, astrocyte proliferation and microglia activation were detected. The expressions of IL-1β and NF-κBp65 in each group were detected meanwhile. Results: At day 14 after seizure, the value of T2 was 84±14 after injecting anti-IL-1β mAb-SPIONs. Compared with the control group, the value of T2 obviously declined. These phenomena of neuron loss, astrocyte proliferation and microglia activation had been improved obviously. IL-1βand NF-κBp65 expression also significantly reduced. Conclusion: Anti-IL-1β mAb-SPIONs can penetrate blood brain barrier and plays an important role in targeting positioning and targeting therapy in temporal lob...Continue Reading

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
