Open loop negative feedback
WebTetraspanin CD81 plays major roles in cell-cell interactions and the regulation of cellular trafficking. This cholesterol-embarking transmembrane protein is a co-receptor for several viruses, including HCV, HIV-1 and Chikungunya virus, which exploits the large extracellular loop EC2 for cell entry. CD81 is also an anticancer target implicated in cancer cell … WebUse feedback to connect the two state-space models in a negative feedback loop according to the above figure. sys = feedback (G,C,-1); size (sys) State-space model with 2 outputs, 2 inputs, and 6 states. The resulting state-space model sys is a 2 input, 2 output model with 6 states.
