Johns Hopkins Medicine scientists say they have developed a nanoparticle — an extremely tiny biodegradable container — that has the potential to improve the delivery of messenger ribonucleic acid (mRNA)-based vaccines for infectious diseases such as COVID-19, and vaccines for treating non-infectious diseases including cancer.
Researchers at IRB Barcelona, the University of Barcelona (UB), VIMM, and the University of Padua unveil the key role of Mitofusin 2 cellular makeup in interconnecting organelles within cells. As essential structures with specialized functions, these organelles rely on intricate connections for seamless communication. Among these organelles, mitochondria (known as cell powerhouses) and the endoplasmic reticulum (responsible for protein and lipid synthesis) engage in vital exchanges.

Healthy human skin is a mosaic-like collection of both normal and mutation-bearing cells. As people age, a growing number of these cells accumulate more and more mutations including those that can cause cancer. Eventually these mutant cells, which are fueled by environmental insults such as high sun exposure, gradually outcompete the healthy cells, making individuals increasingly susceptible to skin cancers.
