However, it is not clear yet whether binding facilitates cellular entry or whether it sequesters the peptides away from the lipid bilayer.
Cardo, L., Sadovnikova, V., Phongtongpasuk, S. , Hodges N. J. & Hannon, M. J. Arginine conjugates of metallo-supramolecular cylinders prescribe helicity and enhance DNA junction binding and cellular activity.
As can been seen from Fig. 7, preincubation with cRGD protected the cells against PDT, likely by blocking the binding by competitive inhibition of the construct with integrins and thus preventing receptor binding and cellular uptake.
Anthrax toxin consists of protective antigen (PA), lethal factor (LF) and edema factor (EF). PA constitutes the receptor-binding and carrier protein, which is responsible for host cell attachment, complex formation with LF and EF, cellular entry of the toxin complex and intracellular release of LF and EF to endocytic organelles or the cytoplasm [5].
Currently, the specific cellular receptors or proteins involved in poxvirus fusion with the plasma membrane and subsequent cellular entry are not known.
In this work, we describe a HA-based hydrogel with the dual functionality of increased CD44-dependent chondrocyte binding and controlled release of gapmer antisense oligonucleotides for unassisted cellular entry and subsequent gene silencing activity.
That is, self-assembled vectors for siRNA delivery must associate strongly enough to remain intact during cellular binding and entry, yet they must dissociate at some point within cells to release their cargo.
Envelope proteins play a crucial role in viral cellular entry and immune recognition.
Proviral factors are host proteins hijacked by viruses for processes essential for virus propagation such as cellular entry and replication.
Cellular entry and intracellular trafficking of siRNA/pDNA/liposome lipoplex is likely to differ from those of the separate lipoplexes.
