Mouse T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory domain (TIGIT) is a newly identified surface protein expressed in regulatory, memory, natural killer (NK), and activated T cells.
Epigenetic marks provide a mechanism for regulatory memory that is passed on to subsequent cellular generations and is vital for maintaining cell-type specific patterns of expression and repression.
We evaluated CD40 expression in IgG4-RD, pSS and HC; the results not only revealed that in IgG4-RD patients CD19+ B lymphocytes expressed a lower frequency of CD40, but that decreased MFI of CD40 was also found in all B-cell subsets including regulatory, memory, and mature B cells from IgG4-RD patients.

KO and WT mice had a similar relative proportion of naive, regulatory and memory CD4+ T-cells in PPs (SI Fig S2 A) and spleen (SI Fig S2 B).
A total of 16 arrays were used to analyze regulatory and memory subsets from eight mice (two arrays per littermate pair, including dye swaps, were used for each comparison).
We identified a collection of genes that changed significantly in their expression in regulatory and/or memory T cells as a consequence of p56Lck deficiency (Figure 6A and B, Table S1).
They also can be classified according to their specific functions (e.g., as helper, cytotoxic, regulatory, or memory T cells).
The study didn't test humans, and it doesn't solve all of motherhood's mysteries, Way acknowledges, but he hopes his team's future studies will determine how long the regulatory T cells' memory lasts and how to extend or boost the response.
In addition a study in Kenyan children found differences in activated T cells and memory regulatory T cells between individuals with S. mansoni only compared to individuals concurrently infected with S. mansoni and Plasmodium falciparum [37].
Finally, we investigated the phenotype of CD4+ T-cells present in the PPs and spleens by examining the relative proportions of naive CD25−CD45Rb+, regulatory CD25+CD45Rb− and memory CD25−CD45Rb− CD4+ T-cells.
Also under inflammatory conditions, there was an enhanced migration of regulatory but not memory B cells in the FTY group compared to the HC group (Fig. S3).
