Lactic Acid Bacteria as Delivery Vehicle for Therapeutics Applications.

Lactic acid bacteria comprise a large group of Gram-positive organisms capable of converting sugar into lactic acid. They have been studied due to their therapeutic potential on the mucosal surface. Among the species, Lactococcus lactis is considered the model bacterium and it has been explored as an important vehicle for providing therapeutic molecules and antigens in the mucosa.

Aptamers as Diagnostic Tools in Cancer.

Cancer is the second leading cause of death worldwide. Researchers have been working hard on investigating not only improved therapeutics but also on early detection methods, both critical to increasing treatment efficacy, and developing methods for disease prevention. The use of nucleic acids, or aptamers, has emerged as more specific and accurate cancer diagnostic and therapeutic tools.
