HIV can be transmitted from an infected mother to the neonate in three circumstances: across the placenta during pregnancy (in utero), at birth due to fetal contact with infected maternal genital secretions and blood, or postnatally through the breast milk. [8] This type of viral transmission is also known of as vertical transmission.
A vertically transmitted infection is an infection caused by pathogenic bacteria or viruses that use mother-to-child transmission, that is, transmission directly from the mother to an embryo, fetus, or baby during pregnancy or childbirth. It can occur when the mother has a pre-existing disease or becomes infected during pregnancy. Nutritional ...
The placenta does not block maternal IgG antibodies, which thereby may pass through the human placenta, providing immune protection to the fetus against infectious diseases. One model for the induction of tolerance during the very early stages of pregnancy is the eutherian fetoembryonic defense system (eu-FEDS) hypothesis. [ 10 ]
Children whose mothers had coronavirus infections during pregnancy were more likely to be diagnosed with neurodevelopmental problems, a study finds. Coronavirus infection during pregnancy linked ...
In two systematic reviews [10] [11] concluded that covid-19 could potentially disrupt the neurodevelopment of the fetus as a consequence of the hyperinflammatory host response elicited by the viral infection through various possible mechanisms. However, it is still a controversial subject due to the complex nature of investigating an ...
HIV-associated neurocognitive disorders (HAND) are neurological disorders associated with HIV infection and AIDS.It is a syndrome of progressive deterioration of memory, cognition, behavior, and motor function in HIV-infected individuals during the late stages of the disease, when immunodeficiency is severe.

First is the 3’ processing of the HIV DNA, followed by strand transfer of the HIV DNA into the host DNA. The integration of HIV DNA can occur either in dividing or resting cells, and the HIV integrase enzyme can exist in the form of a monomer, dimer, tetramer, and possibly even higher-order forms (such as octomers). Each HIV particle has an ...
