abstract = {The ZFP36 family of RNA-binding proteins acts post-transcriptionally to repress translation and promote RNA decay. Studies of genes and pathways regulated by the ZFP36 family in CD4+ T cells have focussed largely on cytokines, but their impact on metabolic reprogramming and differentiation is unclear. Using CD4+ T cells lacking Zfp36 and Zfp36l1, we combined the quantification of mRNA transcription, stability, abundance and translation with crosslinking immunoprecipitation and metabolic profiling to determine how they regulate T cell metabolism and differentiation. Our results suggest that ZFP36 and ZFP36L1 act directly to limit the expression of genes driving anabolic processes by two distinct routes: by targeting transcription factors and by targeting transcripts encoding rate-limiting enzymes. These enzymes span numerous metabolic pathways including glycolysis, one-carbon metabolism and glutaminolysis. Direct binding and repression of transcripts encoding glutamine transporter SLC38A2 correlated with increased cellular glutamine content in ZFP36/ZFP36L1-deficient T cells. Increased conversion of glutamine to $alpha$-ketoglutarate in these cells was consistent with direct binding of ZFP36/ZFP36L1 to Gls (encoding glutaminase) and Glud1 (encoding glutamate dehydrogenase). We propose that ZFP36 and ZFP36L1 as well as glutamine and $alpha$-ketoglutarate are limiting factors for the acquisition of the cytotoxic CD4+ T cell fate. Our data implicate ZFP36 and ZFP36L1 in limiting glutamine anaplerosis and differentiation of activated CD4+ T cells, likely mediated by direct binding to transcripts of critical genes that drive these processes.},

abstract = {Cyclooxygenase (COX) is the key enzyme in prostanoid synthesis from arachidonic acid (AA). Two isoforms, named COX-1 and COX-2, are expressed in mammalian tissues. The expression of COX-2 isoform is induced by several stimuli including cytokines and mitogens, and this induction is inhibited by glucocorticoids (GCs). We have previously shown that the transcriptional induction of COX-2 occurs early after T cell receptor (TCR) triggering, suggesting functional implications of this enzyme in T cell activation. Here, we show that dexamethasone (Dex) inhibits nuclear factor of activated T cells (NFAT)-mediated COX-2 transcriptional induction upon T cell activation. This effect is dependent on the presence of the GC receptor (GR), but independent of a functional DNA binding domain, as the activation-deficient GRLS7 mutant was as effective as the wild-type GR in the repression of NFAT-dependent transcription. Dex treatment did not disturb NFAT dephosphorylation, but interfered with activation mediated by the N-terminal transactivation domain (TAD) of NFAT, thus pointing to a negative cross-talk between GR and NFAT at the nuclear level. These results unveil the ability of GCs to interfere with NFAT activation and the induction of pro-inflammatory genes such as COX-2, and explain some of their immunomodulatory properties in activated human T cells.},

B cell lymphopoiesis requires dynamic modulation of the B cell transcriptome for timely coordination of somatic mutagenesis and DNA repair in progenitor B (pro-B) cells. Here, we show that, in pro-B cells, the RNA-binding proteins T cell intracellular antigen 1 (TIA1) and TIA1-like protein (TIAL1) act redundantly to enable developmental progression. They are global splicing regulators that control the expression of hundreds of mRNAs, including those involved in DNA damage repair. Mechanistically, TIA1 and TIAL1 bind to 5′ splice sites for exon definition, splicing, and expression of DNA damage sensors, such as Chek2 and Rif1. In their absence, pro-B cells show exacerbated DNA damage, altered P53 expression, and increased cell death. Our study uncovers the importance of tight regulation of RNA splicing by TIA1 and TIAL1 for the expression of integrative transcriptional programs that control DNA damage sensing and repair during B cell development.},

Germinal centres (GCs) are a hallmark in the fight against pathogens but they are also the source of most non- Hodgkin’s B cell lymphomas. GCs are distinctive anatomical structures formed in our secondary immune organs, such as spleen and lymph nodes, upon infection. They are not only sites for B cell clonal expansion but the places where the antibody repertoire diversifies. In GCs, B cells undergo affinity maturation. This is the process by which mutagenesis of the immunoglobulin Ig genes followed by cell selection generate antibody- producing cells and memory B cells that protect us against recurrent infections. Tight modulation of Ig somatic hypermutation and DNA damage repair is essential for antibody production, and miss- targeted mutations can lead to chromosomal translocation and B cell tumor transformation.
Understanding how RNA binding proteins enable Ig- class switch recombination and somatic hypermutation in GC B cells while preserving the genome integrity is fundamental in our research. Mutagenesis and DNA repair are highly regulated processes linked to the cell cycle. The existence of different cell cycle checkpoints (at G1, S and M phases) is essential for evaluation and depletion of GC B cells with extensive mutations. RNA binding proteins plays a fundamental role in these processes as they not only control lymphocyte growth and cell cycle progression but also modulate timely translation of key cell cycle checkpoint proteins and DNA damage regulators like p53.
Understanding the complex regulation of lymphocyte development and differentiation requires deep analysis of the cell genome, transcriptome and translatome. The development of next-generation sequencing (NGS) has led to the definition of networks of mRNA molecules that response similarly to a given stimulus. In these early days, recent technologies are capable of both deciphering the RNA binding properties of hundreds of proteins and identify the set of RNA binding proteins associated to a single transcript, but how this knowledge is translated into regulation of lymphocyte function is under intense scrutiny in our lab.
