Then, fitting interaction effects as random effects becomes essential, to allow the effects' constants that are derived from small subclasses to be regressed towards the population mean.
As shown in Figure 1e, although the anti-CII antibodies of both IgG subclasses seemed to be slightly higher in RP105-/ mice, they were not significantly different.
At least five molecular subgroups (basal-like, normal-like, HER2-positive, and luminal A and luminal B) have been identified [ 1, 2] and additional subclasses continue to be suggested [ 3- 7].
In pigs, IFN-γ and IL-12 induced a bias towards IgG2 production; since IL-10 could up-regulate IgG1 levels, the IgG2 subclass is considered to be associated with a Th1-cell-controlled immune response, while the IgG1 subclass is associated with a Th2-cell-controlled response [36].
This subclass was demonstrated to be associated with poor patient survival [ 7, 37].
Finally, the basal-like subclass is known to be negative for HER2/ErbB2, ER and the progesterone receptor (PR), and characterised by the expression of genes from the basal epithelium with high frequency of TP53 mutations (Sorlie et al, 2001; Foulkes et al, 2004; Bertucci et al, 2006; Turner and Reis-Filho, 2006; Yehiely et al, 2006; Adelaide et al, 2007; Jumppanen et al, 2007).
The reduction in IgG-subclass levels appeared to be specific for IgG4.
These two subclasses are known to be deep branching Actinobacteria from systematics studies (Pukall et al. 2010).
Subclasses were considered to be present if a particular domain was determined to set apart a set of peptides from several distinct lineages.
