Although CD4+ T cells have been thought to be distinct lineages defined by the transcription factors they express and the cytokines they produce, there is in fact considerable plasticity in CD4+ T-cell fate 47; indeed, there are several possible combinations of activating and repressive modifications 48.
Sperm samples treated with the other two combinations of activating polymer (2.5 μM each) showed efficacies equal to treatment with a single polymer at 2.5 μM.
Thus, it is possible that the cell type infected and the different combinations of Tlrs activated may have a profound influence on the outcome of the infection.
The resultant model could then be used to give predictions for combinations of agents, activating specific mathematical subsections describing human pharmacology.
These factors then act in combination to activate the expression of several cardiac structural genes, i.e. myosin heavy chain (α-MyHC), myosin light chain (Mlc2V), calcium channel (αCach) and cardiac troponin (cTnI) [20].
For the Gβγ-induced PKD activation, even in the presence of PLCβ2 or PLCβ3, only certain Gβγ dimer combinations are capable of activating the kinase effectively.
The combination of two activated hydrogen atoms will be responsible for part of the observed gas evolution.
The selection and combination of pathways activated ultimately result in changes in gene expression, thereby triggering the appropriate biological response to the extracellular cues received.
As conventional photodynamic therapy would require a light source and not be practical for treatment of malaria, the authors used a combination of luminol activated by an oxygen radical generator (e.g. Artemisinin) to demonstrate that parasites are killed by these in combination with ALA.
The RNA interference technique can be applied in planarians to identify gene functions [ 16], and single-cell level gene profiling is also possible based on a combination of fluorescence activated cell sorting (FACS) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) [ 17, 18].
