Episode 498 - Proteins, MRNA and fighting back against cancer

August 29, 2022

How can we develop new treatments to tackle antibiotic resistance and tumors. Antibiotics were the miracle of public health in the 20th century, but how can we establish new treatments into the 21st. Find the right protein and you can stop bacteria in its tracks by splitting it in two. New treatments can tackle antibiotic resistant bacteria by using proteins to break them in two. Cancer vaccines are benefiting from the mRNA revolution. A challenge with vaccines is that they can end up in the liver, so how do you get them to  deliver their instructions more effectively. Using special lipid nano particles, cancer mRNA vaccines can target the lymph nodes making for more powerful vaccines.
