Histology and immunocytochemical localization of glial fibrillary acidic protein in the inner ear of Scincella tsinlingensis

Int. j. morphol; 39 (2), 2021
SUMMARY: The microstructure of inner ear in Scincella tsinlingensis was observed by light microscopy and the expression of glial fibrillary acidic protein (GFAP) in membranous labyrinth among the juvenile age group, subadult age group and adult age group were also detected by methods of immunohistochemis...

Memory impairments and increased GFAP expression in hippocampal astrocytes following hypercaloric diet in rats

Arq. neuropsiquiatr; 77 (9), 2019
ABSTRACT Objective: Hypothalamic inflammation and glial fibrillary acidic protein (GFAP) overexpression in astrocytes are well described in obese animals, as are some cognitive and memory deficits. As the hippocampus plays important roles in the consolidation of information, this investigation aimed to ...

Preoperative anxiety induces chronic postoperative pain by activating astrocytes in the anterior cingulate cortex region

SUMMARY OBJECTIVE The study aims to explore the relationship between preoperative anxiety and chronic postoperative pain. METHODS A total of forty rats were divided into four groups, control, single-prolonged stress alone, Hysterectomy alone, and SPS+ Hysterectomy. The paw withdrawal mechanical thres...

Entry of rabies virus in the olfactory bulb of mice and effect of infection on cell markers of neurons and astrocytes

Int. j. morphol; 36 (2), 2018
There are few studies of infection by rabies virus in the olfactory bulb (OB). This work was carried out with the purpose of establishing the time required to detect rabies antigens in the OB of mouse, after the intramuscular inoculation of the virus and to evaluate the effect of the infection on the exp...

Curcumin decreases astrocytic reaction after gliotoxic injury in the rat brainstem

Arq. neuropsiquiatr; 75 (8), 2017
ABSTRACT Recent studies have demonstrated that curcumin (Cur) has antioxidant, anti-inflammatory and anti-fibrotic effects. Ethidium bromide (EB) injections into the central nervous system (CNS) are known to induce local oligodendroglial and astrocytic loss, resulting in primary demyelination and neuroin...

Immunohistochemical analysis of retinoblastoma cell phenotype using neuronal and glial cell markers

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: The cellular origin of retinoblastoma is uncertain as constituent tumor cells heterogeneously express markers of both immature and mature retinal cells. An immunohistochemical analysis of cellular origin may yield valuable insights into disease progression and treatment options. This s...
