Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

There are three known isoforms in mammals, two are constitutive (cNOS) and the third is inducible (iNOS). [10] Cloning of NOS enzymes indicates that cNOS include both brain constitutive ( NOS1 ) and endothelial constitutive ( NOS3 ); the third is the inducible ( NOS2 ) gene. [ 10 ]
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [2] The word is from Ancient Greek ἐγκέφαλος, enképhalos 'brain', [37] composed of ἐν, en, 'in' and κεφαλή, kephalé, 'head', and the medical suffix -itis 'inflammation'. [38]
Arachnoiditis is an inflammatory condition of the arachnoid mater or 'arachnoid', one of the membranes known as meninges that surround and protect the central nervous system. The outermost layer of the meninges is the dura mater (Latin for hard) and adheres to inner surface of the skull and vertebrae. [ 1 ]
[27] [28] [29] On the other hand, transforming growth factor-beta (TGF-β) provides a strong inhibitory signal to iNOS, whereas interleukin-4 (IL-4) and IL-10 provide weak inhibitory signals. In this way, the immune system may regulate the armamentarium of phagocytes that play a role in inflammation and immune responses. [30]
The authors argue that their findings suggest excess fat could increase the risk of Alzheimer’s disease due to inflammation in the brain, and that reducing fat and obesity in midlife could ...
'brain'; and the medical suffix -itis, "inflammation"), also known as herpes meningoencephalitis, is a medical condition that simultaneously resembles both meningitis, which is an infection or inflammation of the meninges, and encephalitis, which is an infection or inflammation of the brain tissue.
As more people were added to the study, details of how inflammation from belly fat on the parts of the brain where Alzheimer’s originates came into focus. The brain changes they found were ...
