As the scientific community is seeking alternatives to antibiotic treatment, periodontal researchers found that photodynamic therapy (PDT) is advantageous for suppressing anaerobic bacteria that lead to periodontal diseases according to a recent study in the Journal of Periodontology.
"Although this study is still in its early phase, with the recent number of reports about bacterial strains becoming resistant to frequent doses of antibiotics, PDT could be an alternative to conventional periodontal therapeutic methods," said Michael P. Rethman, D.D.S., M.S., and president of the American Academy of Periodontology. "Antibiotics may be used as an adjunctive therapy for periodontal diseases, so there is a pronounced interest in the development of alternative antimicrobial concepts.
PDT involves two stages. In the first stage, a light-sensitive drug is applied. The second stage involves shining a light or laser directly on the area treated with the drug. When the light is combined with the drug, phototoxic reactions are induced which destroy bacterial cells. PDT was first approved by the Food and Drug Administration in 1999 to treat pre-cancerous skin lesions of the face or scalp.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
