Novel hydrogel slowly releases RNA nanovaccines to shrink tumors


Novel hydrogel slowly releases RNA nanovaccines to shrink tumors
Messenger RNA (mRNA) vaccines to prevent COVID-19 have made headlines around the world recently, but scientists have also been working on mRNA vaccines to treat or prevent other diseases, including some forms of cancer. Now, researchers reporting in ACS
Nano Letters have developed a hydrogel that, when injected into mice with melanoma, slowly released RNA nanovaccines that shrank tumors and kept them from metastasizing.
Cancer immunotherapy vaccines work similarly to mRNA vaccines for COVID-19, except they activate the immune system to attack tumors instead of a virus. These vaccines contain mRNA that encodes proteins made specifically by tumor cells. When the mRNA enters antigen-presenting cells, they begin making the tumor protein and displaying it on their surfaces, triggering other immune cells to seek and destroy tumors that also make this protein. However, mRNA is an unstable molecule that is quic ....

SARS-CoV-2 D614G mutation associated with lower antibody binding

The onset of the COVID-19 pandemic has brought about an international effort to uncover the biology of its causative agent, SARS-CoV-2, and to develop effective and safe antivirals to contain and treat the infection. A new study by a team of researchers in France and Sweden discusses one such study, exploring the relative immunogenicity of the three main structural proteins of the virus. ....
