Figure 6 Simulated time courses of the numbers of (a) bound type 1 faulty receptors, (b) bound type 2 faulty receptors, (c) bound receptors that form themselves into dimers, and (d) dimers/oligomers.
This is because the bound receptors dissociate immediately the time step right after their binding to plasma ionized calcium since they are faulty of type 2. On unbinding, they can convert back into inactivated receptors or faulty receptors which are free to bind again and again very quickly, while the other types of receptors are more stable once bound to calcium.
Figure 4 Simulated time courses of cytosolic calcium concentration above its equilibrium level (pmb{I_{b}=2.4times10^{-4}mbox{ mmol/L}}), using the parameter values given in Tables 1 and 3. Figure 5 Simulated time courses of the numbers of (a) free healthy receptors, (b) type 1 free defective receptors, (c) type 2 free faulty receptors, and (d) bound healthy receptors.
We also observe that, while the number of healthy bound receptors and type 1 defective receptors eventually plateau out to stable levels, the level of type 2 bound faulty receptors keeps on increasing, or it might take quite a bit longer to level off to a steady state level.
In mutant mice with faulty leptin receptors, injections of leptin had no impact on the taste buds' sensitivity.
The finding adds weight to a theory that APOC3 and faulty LDL receptors together play a key role in the elevated lipid levels seen in FCHL, Tall says.
The study is the first to show that insulin enhances L-arginine's effects in people, Giugliano says, and it may help explain why overweight diabetics--who often have faulty insulin receptors--are also at risk for cardiovascular disease.
The feedforward pathway can be perturbed by faulty transmitter receptors on the LMC membrane.
For instance, signals cross the faulty ort6 receptors, but only because the histamine release from photoreceptors is boosted by synaptic feedback.
