A Major Downregulation of Circulating microRNAs in Zika Acutely Infected Patients: Potential Implications in Innate and Adaptive Immune Response Signaling Pathways.

Zika virus (ZIKV) is an arbovirus mainly transmitted by mosquitos of the genus . The first cases of ZIKV infection in South America occurred in Brazil in 2015. The infection in humans causes diverse symptoms from asymptomatic to a syndrome-like dengue infection with fever, arthralgia, and myalgia.

The Torque Teno Virus Titer in Saliva Reflects the Level of Circulating CD4 T Lymphocytes and HIV in Individuals Undergoing Antiretroviral Maintenance Therapy.

Introduction: Torque teno virus (TTV) is a non-pathogenic virus present in body fluids. Its titer in the circulation increases in association with immune suppression, such as in HIV-infected individuals. We evaluated if the TTV titer in saliva from HIV-positive individuals undergoing antiretroviral therapy (ART) was related to the circulating CD4+ T lymphocyte concentration and the HIV titer.
