A breakthrough in diagnostics of autism via the assessment of inhibitory signalling in the brain?

Illusion of Human MindScientists from Harvard University have discovered the probable cause of autism. They were the first ones to connect a specific neurotransmitter in the human brain with the incidence of the disease. Due to this observation the spectrum of knowledge about autism, and thus the diagnostic and therapeutical possibilities regarding autism, would widen. The previous reports described the role of GABA signalling in the pathogenesis of the disease on animal models.

Blood-brain barrier defeated by a trick? The use of viral nanocontainers

iStock_000025815091_FullBlood-brain barrier (BBB) has always posed a challenge for pharmacology. So far, there is no completely effective method to administrate peptide drugs, antibiotics and chemotherapeutic agents through the BBB (intrathecal injections are the alternative). The development of an effective penetration method through the blood-brain barrier would open new possibilities in the treatment of central nervous system (CNS) diseases with peptide drugs. Anand P et al. hit upon an innovative idea to overcome this problem. They used specially modified bacteriophages as nanocontainers full of painkillers, which allowed the application of the substance in the target area of action.
