Brazilian D'Or Institute and L'Oréal R&I develop functional human sensory neurons

D'Or Institute for Research and Education
Peer-Reviewed Publication

Scientists were able to generate, in the laboratory, human neurons responsive to sensorial stimuli. After 5 years of collaboration between the D'Or Institute for Research & Education and L'Oreal R&I, in partnership with UFRJ, Unicamp and Embrapa, the discoveries were published in Frontiers in Molecular Neuroscience.

Mechanism that affects multiplication of dengue virus lineage is discovered

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A study aiming at the development of a dengue vaccine shows that the prevalence of a virus lineage upon the other does not rely on the highest replication rate: it is rather based on the virus' ability in triggering weaker activation of the patient's immune response.

Low-protein diet during pregnancy increases prostate cancer risk in offspring

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Experiments with rats show that intrauterine protein restriction induces sex hormone imbalance, which appears to favor development of cancer in old age. The rate of prostate tumor development reached 50 percent among the old rats submitted to low-protein diet during pregnancy and lactation alike.
