The Role of Cathepsin B in the Degradation of Aβ and in the Production of Aβ Peptides Starting With Ala2 in Cultured Astrocytes

Frontiers in Molecular Neuroscience, 2021
Astrocytes may not only be involved in the clearance of Amyloid beta peptides (Aβ) in Alzheimer's disease (AD), but appear to produce N-terminally truncated Aβ (Aβn−x) independently of BACE1, which generates the N-Terminus of Aβ starting with Asp1 (Aβ1−x)

Effect of Bacterial Amyloid Protein Phenol−Soluble Modulin Alpha 3 on the Aggregation of Amyloid Beta Protein Associated with Alzheimer’s Disease

Biomimetics, 2023
Since the proposal of the brainstem axis theory, increasing research attention has been paid to the interactions between bacterial amyloids produced by intestinal flora and the amyloid β−protein (Aβ) related to Alzheimer’s disease (AD), and it has been ...

Diverse Enzymes With Industrial Applications in Four Thraustochytrid Genera

Frontiers in Microbiology, 2020
Thraustochytrids are heterotrophic fungus-like protists that can dissolve organic matters with enzymes. Four strains, AP45, ASP1, ASP2, and ASP4, were isolated from the coastal water of Taiwan, and respectively identified as Aurantiochytrium sp ...

Vaccine testing of a recombinant activation‐associated secreted protein (ASP1) from Ostertagia ostertagi [PDF]

Parasite Immunology, 2007
SUMMARY Previous vaccination trials against the economically important cattle parasite Ostertagia ostertagi have indicated the protective capacity of activation‐associated secreted proteins (ASPs). The further development of these antigens into a commercial vaccine will require their recombinant expression. The aim of the current study was to clone and

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Exploring and Targeting the Connection of Iron and Copper Homeostasis to Neurodegenerative Diseases

MedComm, Volume 7, Issue 6, June 2026.
Iron and copper dyshomeostasis, along with their interactions with key intrinsically disordered proteins (e.g., Aβ, tau, α‐synuclein) have a strong implication in the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Prion diseases (PrDs), Huntington's disease (HD), Wilson's disease (WD),
