Prions are assemblies of misfolded prion protein that cause several fatal and transmissible neurodegenerative diseases, with the most common phenotype in humans being sporadic Creutzfeldt-Jakob disease (sCJD). Aside from variation of the prion protein itself, molecular risk factors are not well understood. Prion and prion-like mechanisms are thought to underpin common neurodegenerative disorders meaning that the elucidation of mechanisms could have broad relevance.

In white-tailed deer (), closely related females form social groups, avoiding other social groups. Consequently, females infected with chronic wasting disease (CWD) are more likely to infect social group members. Culling has been used to reduce CWD transmission in high-risk areas; however, its effectiveness in removing related individuals has not been assessed.

Alzheimer's disease (AD) is characterised by progressive neurodegeneration with the formation of amyloid beta (Aβ) plaques and neurofibrillary tau tangles in the brain parenchyma. The causes of AD have been attributed to a combination of age-related changes within the brain as well as genetic, environmental and lifestyle factors. However, a recent study by Banerjee et al.

Prion diseases, including Creutzfeldt-Jakob disease (CJD), are deadly neurodegenerative disorders characterized by the buildup of abnormal prion proteins in the brain. This accumulation disrupts neuronal functions, leading to the rapid onset of psychiatric symptoms, ataxia, and cognitive decline. The urgency of timely diagnosis for effective treatment necessitates the identification of strongly correlated biomarkers in bodily fluids, which makes our research crucial.

Prion diseases are fatal neurodegenerative diseases that can be transmitted by infectious protein particles, PrPs, encoded by the endogenous prion protein gene (). The origin of prion seeds is unclear, especially in non-human hosts, and this identification is pivotal to preventing the spread of prion diseases from host animals. Recently, an abnormally high amyloid propensity in prion proteins (PrPs) was found in a frog, of which the genetic variations in the gene have not been investigated.
