1. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects
Sammanfattning : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. LÄS MER
2. Cell-Penetrating Peptides for Mitochondrial Targeting
Sammanfattning : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.

3. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis
Sammanfattning : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. LÄS MER
4. In-silico design of peptide-based transfection systems, in-vitro validation, and up-take pathways investigation
Sammanfattning : Cell-penetrating peptide-based transfection systems (PBTS) are a promising group of drug delivery vectors. Cell-penetrating peptides (CPPs) are short cationic peptides that are able of transporting cell non-permeant cargos into different cell types. LÄS MER
5. Structures, toxicity and internalization of cell-penetrating peptides
Sammanfattning : Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. LÄS MER
