Known antiretroviral restriction factors are encoded by genes that are under positive selection pressure, induced during HIV-1 infection, up-regulated by interferons, and/or interact with viral proteins. To identify potential novel restriction factors, we performed genome-wide scans for human genes sharing molecular and evolutionary signatures of known(More)
Innate immune activation by macrophages is an essential part of host defence against infection. Cytosolic recognition of microbial DNA in macrophages leads to induction of interferons and cytokines through activation of cyclic GMP-AMP synthase (cGAS) and stimulator of interferon genes (STING). Other host factors, including interferon-gamma inducible factor(More)
The proximal part of the epiphysis cerebri of the guinea pig is in close contact with the cerebrosopinal fluid of the third ventricle. A direct contact is not present as the pineal tissue is covered by a continuous ependymal layer. Two types of ependymal cells with different surface protrusions are discussed as being involved in possible interactions(More)
