Dual-acting stapled peptides target both HIV-1 entry and assembly [PDF]

, 2013
Background: Previously, we reported the conversion of the 12-mer linear and cell-impermeable peptide CAI to a cell-penetrating peptide NYAD-1 by using an i,i + 4 hydrocarbon stapling technique and confirmed its binding to the C-terminal domain (CTD ...

Cleavage of the vaspin N-terminus releases cell-penetrating peptides that affect early stages of adipogenesis and inhibit lipolysis in mature adipocytes

Adipocyte, 2021
Vaspin expression and function is related to metabolic disorders and comorbidities of obesity. In various cellular and animal models of obesity, diabetes and atherosclerosis vaspin has shown beneficial, protective and/or compensatory action.

Cell-penetrating peptides [PDF]

Plant Signaling & Behavior, 2008
Internalization of cell-penetrating peptides, well described in mammalian cell system, has recently been reported in a range of plant cells by three independent groups. Despite fundamental differences between animal cell and plant cell composition, the CPP uptake pattern between the mammalian system and the plant system is very similar. Tat, Tat-2 pVEC

Characterisation of cell‐penetrating peptide‐mediated peptide delivery [PDF]

British Journal of Pharmacology, 2005
Cell‐penetrating peptides such as antennapedia, TAT, transportan and polyarginine have been extensively employed for in vitro and in vivo delivery of biologically active peptides. However, little is known of the relative efficacy, toxicity and uptake mechanism of individual protein transduction domain–peptide conjugates, factors that will be critical

Cell-Penetrating Peptides: Applications in Tumor Diagnosis and Therapeutics

Pharmaceutics, 2021
Since their identification over twenty-five years ago, the plethora of cell-penetrating peptides (CPP) and their applications has skyrocketed. These 5 to 30 amino acid in length peptides have the unique property of breaching the cell membrane barrier ...

Ligands for oral delivery of peptides across the blood-brain-barrier

Acta Materia Medica, 2022
Peptides are short chains of amino acids linked by peptide bonds. Many peptides and proteins are limited by their poor enzymatic stability and permeability across the intestinal epithelial membranes and/or blood-brain barrier (BBB).
