Brain p3‐Alcβ peptide restores neuronal viability impaired by Alzheimer's amyloid β‐peptide
We propose a new therapeutic strategy for Alzheimer's disease (AD). Brain peptide p3‐Alcβ37 is generated from the neuronal protein alcadein β through cleavage of γ‐secretase, similar to the generation of amyloid β (Aβ) derived from Aβ‐protein precursor ...

Alzheimer's Disease "Non-amyloidogenic" p3 Peptide Revisited: A Case for Amyloid-α. [PDF]
Amyloid-β (Aβ) is an intrinsically disordered peptide thought to play an important role in Alzheimer's disease (AD). It has been the target of most AD therapeutic efforts, which have repeatedly failed in clinical trials. A more predominant peptidic fragment, formed through alternative processing of the amyloid precursor protein, is the p3 peptide.

Evaluation of the fusion inhibitor P3 peptide as a potential microbicide to prevent HIV transmission in women. [PDF]
Microbicides are an important strategy for preventing the sexual transmission of HIV but, so far, the most advanced tenofovir-based microbicides have had modest efficacy.

Cemp1-p3 Peptide Promotes the Transformation of Octacalcium Phosphate into Hydroxyapatite Crystals [PDF]
Dental cementum contains unique molecules that regulate the mineralization process in vitro and in vivo, such as cementum protein 1 (CEMP1). This protein possesses amino acid sequence motifs like the human recombinant CEMP1 with biological activity. This

Identities of P2 and P3 Residues of H-2Kb-Bound Peptides Determine Mouse Ly49C Recognition. [PDF]
Ly49 receptors can be peptide selective in their recognition of MHC-I-peptide complexes, affording them a level of discrimination beyond detecting the presence or absence of specific MHC-I allele products.

Is the p3 Peptide (Aβ17-40, Aβ17-42) Relevant to the Pathology of Alzheimer's Disease?1. [PDF]
Despite the vast heterogeneity of amyloid plaques isolated from the brains of those with Alzheimer’s Disease (AD), the basis of the Amyloid Cascade Hypothesis targets a single peptide, the amyloid-β (Aβ) peptide. The countless therapeutic efforts targeting the production and aggregation of this specific peptide have been met with disappointment ...

The Alzheimer’s Disease γ-Secretase Generates Higher 42:40 Ratios for β-Amyloid Than for p3 Peptides [PDF]
Alzheimer’s disease is characterized by intracerebral deposition of β-amyloid (Aβ). While Aβ40 is the most abundant form, neurotoxicity is mainly mediated by Aβ42.

Structural analyses and substrate profiling of PPEP-3 provide new insights into the molecular basis of Pro-Pro endopeptidase specificity [PDF]
Summary: Pro-Pro endopeptidases (PPEPs) are secreted bacterial enzymes that uniquely cleave peptide bonds between adjacent proline residues. Their active site accommodates six substrate residues (P3 to P3′), with interactions at these positions ...

Restoring apoptosis in breast cancer via peptide mediated disruption of survivin IAP interaction [PDF]
Apoptosis is a form of programmed cell death mediated by caspases and regulated through both intrinsic and extrinsic pathways. Many cancers evade apoptosis, resulting in uncontrolled cell survival and tumor progression.
