Interaction of Hydrophobic Tungsten Cluster Complexes with a Phospholipid Bilayer

Biomimetic controlled radical photopolymerization in a two-dimensional organized environment under visible light

Fast and well-controlled photoinduced atom transfer radical polymerization (photoATRP) in the organized medium of a bilayer activated by visible light under environmentally friendly mild aqueous conditions leads to polymers with predetermined molecular weight and low dispersity. The decisive parameter for photoATRP of monomers in the organized medium was their mobility and orientation with respect to the bilayer and the photoredox catalyst localized in the interstitial layer.

A splenic-targeted versatile antigen courier: iPSC wrapped in coalescent erythrocyte-liposome as tumor nanovaccine

The major obstacles for tumor vaccine to be surmounted are the lack of versatile property and immunity-inducing effectiveness. Induced pluripotent stem cells (iPSCs) expressed various antigens the same as multiple types of tumors, providing a promising source of wide-spectrum cancer vaccines. The damaged erythrocyte membrane entrapped by spleen could be developed as antigen deliverer for enhancing acquired immunity. Here, the modified lipid materials were used to dilate erythrocyte membrane to fabricate coalescent nanovector, which not only preserved the biological characteristics of erythrocyte membrane but also remedied the defect of insufficient drug loading capacity. After wrapping iPSC protein, the nanovaccine iPSC@RBC-Mlipo exhibited obvious splenic accumulation, systemic specific antitumor immunity evocation, and effective tumor expansion and metastasis inhibition in mice. Hence, our research may provide a prospective strategy of efficient tumor vaccine for clinical practice.
