First, the expression of NK1.1 antigen on NOD DNCD3 splenic cells has been ruled out, since the NOD mouse strain like the C57BL/6 and SJL strains lacks the NK1.1 encoding allele.
Inbred mice strains, like BALB/c, have been extensively used to study mastitis.
Thus, it appears that strain-specific genetic elements dictate that in permissive mouse strains, the ES-like pluripotent state is dominant following iPS reprogramming Murine embryonic fibroblasts (MEFs) of E14 Oct4-GFP (BL6/tgOct4-GFP) were transduced with a cocktail of retroviruses expressing the iPS reprogramming factors (Oct4, Sox2, Klf4 and c-Myc) as shjown schematically in (Figure 1A).
Although the number of LF present in the salivary and lacrimal glands does not often correlate directly with disease or its severity, SS patients and NOD-derived mouse strains exhibiting SS-like disease typically have lymphocytic infiltrates in their salivary glands.
Thus, the genetically determined capacities to control TB and M. avium-triggered disease in these two mouse strains are indeed mirror-like.
Our results, obtained in two treatment protocols on two mouse strains, suggest an antidepressant-like effect of used here dosing with T2.
This was first shown in mice: certain inbred mouse strains have a Th1 bias (like C57BL/6) and others have a Th2 bias (like Balb/c).
Whilst these data were suggestive of genetic determination of GTM profiles, further analyses was necessary to differentiate between environmental and genetic factors, since individual mouse strains were housed together with like strains and familial GTM profiles could be perpetuated through maternal contact and by coprophagia.
This situation would be analogous to MMTV infection-susceptible congenic mouse strains, which retain endogenous MMTV-like sAg genes that delete sAg-binding T cells with the same Vβ specificities as those encoded by the infectious virus during the shaping of the TCR repertoire (reviewed in [67]).
Remarkably, this could be calibrated as a simple threshold trait, i.e. a binary 'yes no' response, which after crossing the two mouse strains behaved as a dominant-like trait.
