A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

If a host cell expresses the complementary surface receptor for the virus, then the virus can attach and enter the cell. If a cell does not express these receptors, then the virus cannot normally infect it. Therefore, if the virus cannot bind to the cell, it does not display tropism for that host. Bacteria infect hosts differently than viruses ...
If the transgene is incorporated into somatic cells, the transgene will stay with the somatic cell line, and thus its host organism. [ 6 ] Gene delivery is a necessary step in gene therapy for the introduction or silencing of a gene to promote a therapeutic outcome in patients and also has applications in the genetic modification of crops.
HCPs in biopharmaceutical products pose a potential safety risk to humans by introducing foreign proteins and biomolecules to the human immune system.Since common host cells used to produce biopharmaceutical drugs are E. coli, [8] yeast, [9] mouse myeloma cell line [10] and Chinese hamster ovary (), [11] the resultant HCPs are genetically different to what the human body [12] recognizes.
Endothelial cell tropism or endotheliotropism is a type of tissue tropism or host tropism that characterizes an pathogen's ability to recognize and infect an endothelial cell. Pathogens, such as viruses, can target a specific tissue type or multiple tissue types.
After being inserted in the host, the gene may be integrated into the host DNA, causing permanent expression, or not integrated, causing transient expression. Heterologous expression can be done in many types of host organisms. The host organism can be a bacterium, yeast, mammalian cell, or plant cell. This host is called the "expression system".
Typically the cells are incubated in a solution containing divalent cations (often calcium chloride) under cold conditions, before being exposed to a heat pulse (heat shock). Calcium chloride partially disrupts the cell membrane, which allows the recombinant DNA to enter the host cell. Cells that are able to take up the DNA are called competent ...
The viral genome is composed of RNA, which enters the cell through receptor-mediated endocytosis. From there, the RNA acts as a template for complementary RNA synthesis. The complementary strand acts as a template for the production of new viral genomes that are packaged and released from the cell ready to infect more host cells.
