Optical coherence tomography reveals heterogeneity of the brain tissue and vasculature in the ischemic region after photothrombotic stroke in mice.

Acta Neurobiol Exp (Wars) 2022 ;82(1):106-119

Nencki Institute of Experimental Biology, Polish Academy of Sciences, Warsaw, Poland;

We demonstrate in vivo imaging of the ischemic area in the mouse brain after photostroke using a custom prototype Gaussian‑beam optical coherence tomography (OCT) setup in which the near infrared imaging beam and the green photoinducing light pass through the same objective lens. The goal of our research was analysis of vascularity of the ischemic area during 2‑week progress of stroke and correlating the hypo‑ and hyperreflective OCT scattering areas with the location of activated microglia and astroglia. Angiogenesis, which was assessed using angiomaps, showed that the area of vessels in the ischemic center increased until day 7. Read More

Identification of microRNA/target gene in the dentate gyrus of 7‑day‑old mice following isoflurane exposure.

Acta Neurobiol Exp (Wars) 2022 ;82(1):96-105

Institute of Neurobiology, School of Basic Medical Sciences, Xi'an Jiaotong University Health Science Center, Xi'an, China.

Studies on rodents and nonhuman primates suggest that exposure to anesthetics, particularly in the young brain, is associated with neuronal apoptosis as well as hippocampal‑dependent cognitive dysfunction. Disruption of the development of dentate gyrus may play an important role in anesthetics‑induced neurotoxicity. However, the anesthetics triggered molecular events in the dentate gyrus of the developing brain are poorly understood. Read More

Acta Neurobiol Exp (Wars) 2021 ;81(4):314-327

Institute of Neuroscience and Medicine (INM‑10), Research Centre Jülich GmbH, Germany.

Alzheimer's disease (AD) is a common neurodegenerative disease with a prevalence estimated to reach 115 million by 2050. It is characterized by abnormal extracellular accumulation of amyloid‑beta (Aβ) peptide and intracellular neurofibrillary tangles (NFTs) that result in neuro‑inflammation, synaptic dysfunction, neurotransmitter imbalance, neuronal loss, and dendritic changes. A hypothesis of neurotrophic factor (NTF) involvement in neurodegenerative diseases and their potential as a therapeutic tool has emerged. Read More

Annexin A3: a newly identified player in store‑operated calcium entry.

Acta Neurobiol Exp (Wars) 2021 ;81(4):307-313

Laboratory of Neurodegeneration, International Institute of Molecular and Cell Biology, Warsaw, Poland;

Store‑operated calcium entry (SOCE) is important for refilling endoplasmic reticulum (ER) Ca2+ stores and Ca2+ signaling. Extracellular Ca2+ is conducted by highly Ca2+‑selective Orai channels that are activated by stromal interaction molecule proteins (STIMs), which are sensitive ER Ca2+ sensors. We found an approximately five‑fold increase in annexin A3a (anxa3a) expression levels in stim2b knockout zebrafish. Read More
