CD4 + Th2 cell PSI (i.e., proportion of single cells secreting Th2 cytokines IL4, IL5, IL10, and IL13 multiplied by the signal intensity of those cytokines) is significantly greater in clinical nonresponders to therapy (n = 10) versus responders (n = 17). B, CD4 + Th2 cell PSI is associated with inferior peak change in tumor burden per RECIST1 ...

Optimizing Flotation Cells
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.

Th2 Cells in Health and Disease
Helper T (Th) cell subsets direct immune responses by producing signature cytokines. Th2 cells produce IL-4, IL-5, and IL-13, which are important in humoral immunity and protection from helminth infection and are central to the pathogenesis of many allergic inflammatory diseases. Molecular analysis of Th2 cell differentiation and maintenance of ...

Therefore, Th2 cell commitment must be regulated in vivo by additional mechanisms. One possibility is that CD4 + T cells default into the Th2 cell pathway in the presence of strong IL-2 signaling but the absence of positive signals (or cytokines) that drive differentiation into other Th lineages, particularly into Th1 cells (31–33, 84, 85 ...
