AI Article Synopsis
Article Abstract
Experiments on rats have showed that neurodegenerative damage to the brain induced by injection of a neurotoxic β-amyloid protein fragment β25-35into the basal giant cell nuclei of Meynert activated caspase-3 in the prefrontal cortex and hippocampus on day 3 after injury. Intranasal administration of antibodies to glutamate in a dose of 300 μ g/kg 1 h after damage reduced enzyme activity in these structures in a rat model of Alzheimer's disease.

Circulating sexual stages of ) can be transmitted from humans to mosquitoes, thereby furthering the spread of malaria in the population. It is well established that antibodies can efficiently block parasite transmission. In search for naturally acquired antibodies targets on sexual stages, we established an efficient method for target-agnostic single B cell activation followed by high-throughput selection of human monoclonal antibodies (mAbs) reactive to sexual stages of in the form of gametes and gametocyte extracts.

The central nervous system (CNS) is not an immune-privileged compartment, but it is intimately intertwined with the immune system. Among the components shared by the two compartments is the complement, a main constituent of innate immunity, which is also produced centrally and controls the development and organization of synaptic connections. Complement is considered a doubled-faced system that, besides controlling the physiological development of the central network, also subserves synaptic engulfment pivotal to the progression of neurodegenerative diseases.

New Onset Refractory Status Epilepticus (NORSE) is a rare and severe condition characterized by refractory seizures in individuals without a prior history of epilepsy. This case report describes a 37-year-old woman diagnosed with anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-positive encephalitis-related NORSE. Her seizures were refractory to multiple interventions, including anti-seizure medications, anesthetics, immunotherapies, a ketogenic diet, and electroconvulsive therapy.

Isolated ophthalmoplegia as an anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-associated neurological syndrome is rare. We present a case of a 22-year-old pregnant Hispanic female patient who presented initially with a left oculomotor nerve palsy following an emergency department (ED) visit for migraine headache. Brain imaging was done with no important findings.

Unlabelled: Background Monosodium glutamate (MSG) in its anionic form, glutamate, is one of the main excitatory amino acids. Excess of this neurotransmitter may lead to excitotoxicity affecting neurons and astrocytes responsible for glutamate metabolism in different brain areas of animals. The aim of the study was to investigate the immunoreactivity of glial fibrillary acidic protein (GFAP) and S100β protein in the caudate nucleus of rats under the condition of elevated glutamate levels.
