mRNA therapeutics is revolutionizing the treatment concepts toward many diseases including cancer. The potential of mRNA is, however, frequently limited by modest control over site of transfection. Here, we have explored a library of multivalent ionizable lipid-polypeptides (MILP) to achieve robust mRNA complexation and tumor-confined transfection.

Platinum(II)-based antitumor drugs are widely used in clinics but limited by severe side effects and resistance. Multi-target Platinum(IV) complexes are emerging as ideal alternatives. Heme oxygenase-1 (HO-1) works as a rate-limiting step in heme degradation and is overexpressed in malignant tumors.

It has become increasingly recognized that neural signals can profoundly influence the prognosis of various cancer types. In the past years, we have witnessed "cancer neuroscience," which primarily focuses on the complex crosstalk between tumors and neural signals, emerging as a new, multidisciplinary direction of biomedical science. This review aims to summarize the current knowledge of this research frontier, with an emphasis on the neuroimmune mechanisms enacted through the reciprocal interactions between tumors and the central or peripheral nervous system.

Combination therapies using checkpoint inhibitors with immunostimulatory agonists have attracted great attention due to their synergistic therapeutic effects for cancer treatment. However, such combination immunotherapies require specific timing of doses to show sufficient antitumor efficacy. Sequential treatment usually requires multiple administrations of the individual drugs at specific time points, thus increasing the complexity of the drug regimen and compromising patient compliance.

Antibodies (Basel)

Bispecific antibodies represent a promising class of biologics for cancer treatment. However, their dual specificity and complex structure pose challenges in the engineering process, often resulting in molecules with good functional but poor physicochemical properties. To overcome limitations in the properties of an anti-5T4 x anti-CD3 (α5T4 x αCD3) DART molecule, a phage-display method was developed, which succeeded in simultaneously engineering cross-reactivity to the cynomolgus 5T4 ortholog, improving thermostability and the elevating expression level.
