Abstract
There is growing evidence that certain antibiotics exert their beneficial effects not only by killing or inhibiting the growth of bacterial pathogens but also indirectly by immunomodulation. This review aims at giving an overview of the immunomodulatory properties of antibiotics in different diseases: The antiinflammatory properties of macrolides in chronic inflammatory pulmonary disorders were recognized more than 15 years ago and have been well documented in the last decade. Recent data suggest that several antibiotics such as tetracyclines and cephalosporins may have a beneficial immunomodulatory or neuroprotective effect on neuroimmunological and neurodegenerative diseases including multiple sclerosis and amyotrophic lateral sclerosis. Moreover, the non-bacteriolytic but bactericidal antibiotics rifampicin, clindamycin and aminoglycosides kill bacteria without releasing high quantities of proinflammtory cell wall components. The use of bactericidal, non-bacteriolytic protein synthesis inhibitors reduces mortality and long-term sequelae in experimental bacterial sepsis, plague and meningitis. Clinically, macrolides have been well established as an adjunctive treatment to β- lactam antibiotics in pulmonary diseases. For other indications, appropriate clinical trials are necessary before using the immunomodulatory properties of antibiotics in clinical practice.

Common mechanisms underpinning neurodevelopmental disorders and psychiatric diseases
A growing number of large-scale epidemiologic studies has strongly suggested that common mechanisms may be shared by aberrant brain development and psychiatric disorders. There is now an appreciation of synergic roles of genetic variants and environmental stress which profoundly affect the genome integrity and reshape brain development. This can lead ...read more
