COVID-19 and the human innate immune system

COVID-19: The potential role of nutritional deficiencies, global climatic changes, and immune system dysfunction

The innate immune system

The innate immune system ; is an important subsystem of the overall immune response system that comprises the cells and mechanisms that defend the host from infection by other organisms. The cells of the innate system recognize and respond to pathogens in a generic way, but, unlike the adaptive immune system, the system does not confer long-lasting or protective immunity to the host. Innate imm...

Modelling the Innate Immune System

The Human Immune System (HIS) is a complex network composed of specialized cells, tissues, and organs that is responsible for protecting the organism against diseases caused by distinct pathogenic agents, such as viruses, bacteria and other parasites. The first line of defence against pathogenic agents consists of physical barriers of skin and the mucous membranes. If the pathogenic agents brea...

Innate Immune System and Preeclampsia

Normal pregnancy is considered as a Th2 type immunological state that favors an immune-tolerance environment in order to prevent fetal rejection. Preeclampsia (PE) has been classically described as a Th1/Th2 imbalance; however, the Th1/Th2 paradigm has proven insufficient to fully explain the functional and molecular changes observed during normal/pathological pregnancies. Recent studies have e...

Expression of an Innate Immune Element (Mouse Hepcidin-1) in Baculovirus Expression System and the Comparison of Its Function with Synthetic Human Hepcidin-25

Hepcidin is an innate immune element which decreases the iron absorption from diet and iron releasing from macrophage cell. In contrast to the chemical iron chelators, there has been limited effort applied to the specific use of hepcidin as a new drug for decreasing the iron overload. Hepcidin is produced in different biological systems. For instance, E-coli is used for human hepcidin expressio...
