Natural killers (NK) cells are unique innate immune cells that increase up to fivefold in the circulating blood with brief exercise and are known to play a key role in first-response defense against pathogens and cancer immunosurveillance. Whether exercise alters NK cell gene and microRNA (miRNA) expression is not known. Thirteen healthy men (20-29 yr old) performed ten 2-min bouts of cycle ergometer exercise at a constant work equivalent to an average of 77% of maximum O2 consumption interspers ...[more]

Effects of exercise on gene expression level in human NK Cells

Project description:We tested the hypothesis on the mechanisms responsible for the early control of NK cell function by identifying a discrete set of genes in circulating NK cells that were altered by exercise. Exercise leads to a rapid change in the profile of gene expression in NK cells. Twelve healthy men (20-29 yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about 77% of VO2max. A baseline blood sample was taken before the and immediately after the exercise. NK cells were isolated from PBMC using a negative magnetic cell separation methods (Miltenyi Biotec Kit #130-092-657 and the autoMACSM-BM-. Pro Separator). Total RNA was extracted using TRIzolM-BM-.. For this study we used Affymetrix plus 2 (total of 24 chips).

We hypothesized that microRNA expression in circulating monocytes would also be affected by brief exercise. Twelve healthy men (22-30yr old) performed 10 2-min bouts of cycle ergometer exercise interspersed with 1-min rest at a constant work equivalent to about82% of VO2max. A baseline blood sample was taken before the and immediately after the exercise.

Single-cell characterization of immune aplastic anemia reveals convergence of adaptive and innate immunity: in vitro

Project description:Immune aplastic anemia (AA) is a life-threatening bone marrow (BM) failure disorder driven by an autoimmune T cell attack against the hematopoietic stem and progenitor cells (HSPCs). However, the autoantigen targets and the role of other immune cells are unknown. Here, by combining scRNA+TCRαβ-seq, TCRβ-seq, flow cytometry and plasma cytokine profiling of >250 patients with AA, >250 patients with other hematological disorders and >1,000 healthy controls, we identify NK cells and CD8+ TEMRA cells expressing NK receptors with AA-associated TCRB-seq motifs as the most dysregulated immune cell populations in AA BM. Functional co-culture experiments with scRNA-TCRαβ-seq readout utilizing primary HSPCs and immune cells (in total 55 conditions) provide evidence that NK cells alone cannot kill HSPCs, but sensitize them to CD8+ T cell mediated killing. Furthermore, HSPCs induce strong activation of T cell clones with CD8+ TEMRA NK-like phenotype and AA-associated TCR motifs. To conclude, our results reveal convergent evolution of innate and adaptive immune cells in AA, where NK cells support CD8+ T cell mediated autoimmunity.

Nanomaterials trigger functional responses in primary human immune cells

Project description:Targeting the immune system with nanoparticles (NPs) to deliver immunomodulatory molecules emerged as a solution to address intra-tumoral immunosuppression and enhance therapeutic response. While the potential of nanoimmunotherapies in reactivating immune cells has been evaluated in several preclinical studies, the impact of drug-free nanomaterials on the immune system remains unknown. Here, we characterize the molecular and functional response of human NK cells and pan T cells to two NPs that are commonly used in biomedical applications: ultrasmall silica-based gadolinium (Si-Gd) NPs and poly(lactic-co-glycolic acid) (PLGA) NPs. Bulk RNA-sequencing analysis showcase that PLGA NPs trigger a transcriptional priming towards activation in NK and T cells. While PLGA NPs improved NK cells anti-tumoral functions in a cytokine-deprived environment, Si-Gd NPs significantly impaired T cells activation as well as functional responses to a polyclonal antigenic stimulation . Altogether, we identified PLGAs NPs as suitable and promising candidates for further targeting approaches aiming to reactivate the immune system of cancer patients.

TOX2 regulates human natural killer cell development by controlling T-BET expression

Project description:Thymocyte selection-associated high mobility group box protein family member 2 (TOX2) is a transcription factor belonging to the TOX family that shares a highly conserved high mobility group DNA binding domain with the other TOX members. While TOX1 has been shown to be an essential regulator of T-cell and natural killer (NK) cell differentiation in mice, little is known about the roles of the other TOX family members in lymphocyte development, particularly in humans. In this study, we found that TOX2 was preferentially expressed in mature human NK cells and was upregulated during in vitro differentiation of NK cells from human umbilical cord blood (UCB)M-bM-^@M-^Sderived CD34+ cells. Gene silencing of TOX2 intrinsically hindered the transition between early developmental stages of NK cells, while overexpression of TOX2 enhanced the development of mature NK cells from UCB CD34+ cells. We subsequently found that TOX2 was independent of ETS-1 but could directly upregulate the transcription of TBX21 (encoding T-BET). Overexpression of T-BET rescued the TOX2 knockdown phenotypes. Given the essential function of T-BET in NK cell differentiation, TOX2 therefore plays a crucial role in controlling normal NK cell development by acting upstream of TBX21 transcriptional regulation. survey of NK cells over time
