Abstract
The formation of senile plaques containing amyloid β peptides (Aβ peptides) as a major constituent plays a significant role in development of Alzheimers disease. The concentration of Aβ peptides in the brain is determined by a combination of their rate of synthesis and their rate of clearance. Considerable effort has been expended in producing inhibitors of the β and γ secretases involved in the synthesis of the Aβ peptides. More recently interest in the mechanism of clearance of the Aβ peptides has emerged, as promoting Aβ peptide clearance represents an alternative therapeutic approach. It now appears that cleavage of Aβ peptide by peptidases and proteases represents the major mechanism of clearance. This review describes those peptidases and proteases implicated in Aβ peptide clearance, the evidence that these enzymes function in vivo, and how they may represent new therapeutic targets.

Blood-based biomarkers in large-scale screening for neurodegenerative diseases
Disease biomarkers are necessary tools that can be employ in several clinical context of use (COU), ranging from the (early) diagnosis, prognosis, prediction, to monitor of disease state and/or drug efficacy. Regarding neurodegenerative diseases, in particular Alzheimer’s disease (AD), a battery of well-validated biomarkers are available, such as cerebrospinal fluid ...read more

Emerging and re-emerging diseases
Faced with a possible endemic situation of COVID-19, the world has experienced two important phenomena, the emergence of new infectious diseases and/or the resurgence of previously eradicated infectious diseases. Furthermore, the geographic distribution of such diseases has also undergone changes. This context, in turn, may have a strong relationship with ...read more
