Prion is an infectious particle composed of an abnormal isoform of the prion protein (PrPSc) and causes prion diseases such as bovine spongiform encephalopathy (BSE), Creutzfeldt-Jakob disease (CJD) and scrapie. Host cells express cellular prion protein (PrPC), which plays roles in normal functions such as anti-oxidative stress. PrPSc is derived from PrPC and produced by conformational conversion. Prion is notorious as a resistant pathogen, being difficult to inactivate with conventional sterilization procedures. Therefore, to prevent prion-caused iatrogenic diseases, the use of appropriate procedures to inactivate prions is important. For examples, alcohol treatment, autoclave (121˚C, 20 min) and γ-ray irradiation, which are used for disinfection, antisepsis or sterilization of viruses and bacteria, are not effective against prion. This is a fundamental review of prions and methods of their inactivation.

-methyladenosine (mA) is a widespread post-transcriptional modification of RNA in eukaryotes. The conserved YTH-domain-containing RNA binding protein has been widely reported to serve as a typical mA reader in various species. However, no studies have reported the mA readers in ().

The brain contains many interconnected and complex cellular and molecular mechanisms. Injury to the brain causes permanent dysfunctions in these mechanisms. So, it continues to be an area where surgical intervention cannot be performed except for the removal of tumors and the repair of some aneurysms.

As the global population ages, the rising prevalence of neurodegenerative diseases, characterized by abnormal protein aggregates, presents significant challenges for early diagnosis and disease monitoring. Identifying accessible tissue biomarkers is crucial for advancing our ability to detect and track the progression of these diseases. Among the most promising biomarkers is the skin, which shares a common embryological origin with the brain and central nervous system (CNS).

Regarding Alzheimer's disease (AD), specific neuronal populations and brain regions exhibit selective vulnerability. Understanding the basis of this selective neuronal and regional vulnerability is essential to elucidate the molecular mechanisms underlying AD pathology. However, progress in this area is currently hindered by the incomplete understanding of the intricate functional and spatial diversity of neuronal subtypes in the human brain.

Prion diseases, or transmissible spongiform encephalopathies (TSEs), are a group of invariably fatal neurodegenerative disorders. One of the candidate genes involved in prion diseases is the shadow of the prion protein () gene. Raccoon dogs, a canid, are considered to be a prion disease-resistant species.
