In every disease of a human body there is a contribution of a specific protein. When any abnormalities occur in the body, a specific protein secreted in the affected region.
Webb13 mars 2024 · Under conditions of proteotoxic stress, cellular aging, or the presence of disease mutations, proteins can escape a cell’s quality control system and begin to aggregate into non-native structures, which range from oligomers and amorphous assemblies to highly ordered amyloid fibrils and plaques. WebbSnakebite envenoming is a neglected tropical disease (NTD) that results from the injection of snake venom of a venomous snake into animals and humans. In Africa (mainly in sub-Saharan Africa), over 100,000 envenomings and over 10,000 deaths per annum from snakebite have been reported. Difficulties in snakebite prevention and antivenom …
Webb22 apr. 2024 · If cells succeed at triage, they survive, but the protein is unavailable to complete its function, and disease consequences are termed a loss-of-function. If cells fail to remove the aberrant protein, a common outcome is cellular toxicity and even cell death, and the resulting disease phenotype is a so-called toxic gain-of-function. Webb21 apr. 2010 · The principal toxic effects of these structures may include alterations in transcription, impairment of the ubiquitin–proteasome system, mitochondrial dysfunction, dysregulation of intracellular Ca 2+ homeostasis, impairment of axonal transport, and genotoxic stress in polyglutamine diseases.

Webbof accumulated toxic material is known as “membrane trafficking”. This is the process by which membrane “cargo” (proteins and lipids) is moved around the cell. When this process fails, toxic proteins accumulate, and Alzheimer’s disease develops. Membrane trafficking is like a postal service.
