Researchers study the behavior of regulatory T cells to understand periodontal disease
In diseases characterized by bone loss -such as periodontitis, rheumatoid arthritis, and osteoporosis- there is a lot that scientists still don t understand. What is the role of the immune response in the process? What happens to the regulatory mechanisms that protect bone?
In a paper published recently in
Scientific Reports, researchers from the Forsyth Institute and the Universidad de Chile describe a mechanism that unlocks a piece of the puzzle. Looking at periodontal disease in a mouse model, scientists found that a specific type of T cell, known as regulatory T cells, start behaving in unexpected ways. These cells lose their ability to regulate bone loss and instead begin promoting inflammation.

Study shows how new antibiotic resistance genes arise from random DNA sequences
An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal
PLOS Genetics.
Antibiotic resistance is a major global problem and the spread of resistant bacteria causes disease and death, and constitutes a major cost to society. The most common way for bacteria to develop resistance is by taking up various types of resistance genes from other bacteria. These genes encode proteins (peptides) that can lead to resistance by: (i) deactivating the antibiotic, (ii) reducing its concentration, or (iii) altering the antibiotic s target so that the antibiotic can no longer bind to that target and hence halt the growth of the bacterium.
