SARS-CoV-2 Antibodies Detected in Mother's Milk Post-Vaccination.

Background: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic has infected over 127 million people worldwide, with almost 2.8 million deaths at the time of writing. Since no lactating individuals were included in initial trials of vaccine safety and efficacy, research on SARS-CoV-2 vaccination in lactating women and the potential transmission of passive immunity to the infant through mother's milk is needed to guide patients, clinicians, and policy makers on whether to recommend immunization during the worldwide effort to curb the spread of this virus.

The key role of T cells in Parkinson's disease pathogenesis and therapy.

This review focuses on the role of T lymphocytes in the pathogenesis of Parkinson's disease and highlights evidence for modulation of the T cell response as an effective neuroprotective strategy. In preclinical models of Parkinson's disease, modulation of the T cell response results in neuroprotection. Peripheral markers of T cell response show changes in Parkinson's patients relative to controls that have potential application as diagnostic and therapeutic biomarkers.
