Vaccine Efficacy Denial: A Growing Concern Affecting Modern Science, and Impacting Public Health.

The discovery of the vaccination technique was revealed by Edward Jenner in 1796, which represented the first scientific attempt to control an infectious disease by vaccines, followed by other important studies carried out by Pasteur and Koch, and Sabin, who developed the first technique to attenuate the virus. In recent decades, numerous scholars have begun to create dangerous theories against the effectiveness of vaccines through scientifically invalid or fraudulent studies. This critical review of the literature aims to analyze the main factors that have undermined the credibility of vaccines in the general population, disproved false information and emphasized the benefits of vaccines over the last 200 years.

Exosomes from Human Periapical Cyst-MSCs: Theranostic Application in Parkinson's Disease.

The scientific community continuously strives to get new disease models, to discover early markers or novel therapeutic approaches, improving the diagnosis and prognosis of several human pathologies. Parkinson's Disease (PD) is characterized by a long asymptomatic phase, characterized by a selective loss of dopaminergic neurons. Recently, the human Periapical Cyst-Mesenchymal Stem Cells (hPCy-MSCs) have been differentiated in functional dopaminergic neurons: such oral-derived MSCs and the hPCy-MSCs-derived exosomes may represent a strategic and useful study-model, as well as intriguing therapeutic carriers.
