Abstract
Background In this exploratory study, the impact of local irradiation on systemic changes in stress and immune parameters was investigated in eight patients treated with intensity-modulated radiation therapy (IMRT) or stereotactic ablative body radiotherapy (SABR) for prostate adenocarcinoma to gain deeper insights into how radiotherapy (RT) modulates the immune system. Patients and methods RT-qPCR, flow cytometry, metabolomics, and antibody arrays were used to monitor a panel of stress- and immune-related parameters before RT, after the first fraction (SABR) or the first week of treatment (IMRT), after the last fraction, and 3 weeks later in the blood of IMRT (N = 4) or SABR (N = 4) patients. Effect size analysis was used for comparison of results at different timepoints. Results Several parameters were found to be differentially modulated in IMRT and SABR patients: the expression of TGFB1, IL1B, and CCL3 genes; the expression of HLA-DR on circulating monocytes; the abundance and ratio of phosphatidylcholine and lysophosphatidylcholine metabolites in plasma. More immune modulators in plasma were modulated during IMRT than SABR, with only two common proteins, namely GDF-15 and Tim‑3. Conclusion Locally delivered RT induces systemic modulation of the immune system in prostate adenocarcinoma patients. IMRT and SABR appear to specifically affect distinct immune components.

Abstract
The production of T cell receptor αβ(+) (TCRαβ(+) ) T lymphocytes in the thymus is a tightly regulated process that can be monitored by the regulated expression of several surface molecules, including CD4, CD8, cKit, CD25 and the TCR itself, after TCR genes have been assembled from discrete V, D (for TCR-β) and J gene segments by a site-directed genetic recombination. Thymocyte differentiation is the result of a delicate balance between cell death and survival: developing thymocytes die unless they receive a positive signal to proceed to the next stage. This equilibrium is altered in response to various physiological or physical stresses such as ionizing radiation, which induces a massive p53-dependent apoptosis of CD4(+) CD8(+) double-positive (DP) thymocytes. Interestingly, these cells are actively rearranging their TCR-α chain genes. To unravel an eventual link between V(D)J recombination activity and thymocyte radio-sensitivity, we analysed the dynamics of thymocyte apoptosis and regeneration following exposure of wild-type and p53-deficient mice to different doses of γ-radiation. p53-dependent radio-sensitivity was already found to be high in immature CD4(-) CD8(-) (double-negative, DN) cKit(+) CD25(+) thymocytes, where TCR-β gene rearrangement is initiated. However, TCR-αβ(-) CD8(+) immature single-positive thymocytes, an actively cycling intermediate population between the DN and DP stages, are the most radio-sensitive cells in the thymus, even though their apoptosis is only partially p53-dependent. Within the DP population, TCR-αβ(+) thymocytes that completed TCR-α gene recombination are more radio-resistant than their TCR-αβ(-) progenitors. Finally, we found no correlation between p53 activation and thymocyte sensitivity to radiation-induced apoptosis.

Abstract
DNA lesions, including oxydated bases, nucleotide damage and double strand breaks, are continuously produced in living cells and represent a threat for genetic stability. Highly conserved repair processes have evolved to maintain DNA integrity. Cadmium (Cd) is an environmental carcinogenic pollutant known to inactivate several proteins involved in DNA repair systems while at the same time creating an oxidative stress that can result in additional DNA lesions. Cd also has potent immunotoxic effects. DNA repair by non-homologous end joining (NHEJ) is absolutely required for T lymphocyte differentiation. In this study, we examined the impact of Cd on non-homologous end joining pathway by analyzing T cell development in the thymus of mice that received Cd-supplemented drinking water. In vivo, the absence of major alteration indicates that Cd does not affect NHEJ, despite its accumulation in the thymus. Cd contamination affects only a discrete population of developing thymocytes. However, these cells are functional as the cellular response observed in mice following gamma-radiation exposure is identical in treated and control mice. Furthermore, Cd diet did not perturb the redox status in thymocytes and more importantly did not generate significant DNA lesions in organs that accumulate the highest concentration of Cd. Our results show that in vivo, Cd does not affect NHEJ or base and nucleotide repair, and that Cd toxicity to T cells is rather linked to cell cycle perturbations.

Abstract
During thymocyte differentiation, TCRA genes are massively rearranged only after productively rearranged TCRB genes are expressed in association with pTalpha and CD3 complex molecules within a pre-TCR. Signaling from the pre-TCR via the CD3 complex is thought to be required to promote TCRA gene accessibility and recombination. However, alphabeta(+) thymocytes do develop in pTalpha-deficient mice, showing that TCRalpha-chain genes are rearranged, either in CD4(-)CD8(-) or CD4(+)CD8(+) thymocytes, in the absence of pre-TCR expression. In this study, we analyzed the TCRA gene recombination status of early immature thymocytes in mutant mice with arrested thymocyte development, deficient for either CD3 or pTalpha and gammac expression. ADV genes belonging to different families were found rearranged to multiple AJ segments in both cases. Thus, TCRA gene rearrangement is independent of CD3 and gammac signaling. However, CD3 expression was found to play a role in transcription of rearranged TCRalpha-chain genes in CD4(-)CD8(-) thymocytes. Taken together, these results provide new insights into the molecular control of early T cell differentiation.

Abstract
Pre-TCR expression on developing thymocytes allows cells with productive TCRB gene rearrangements to further differentiate. In wild-type mice, most TCRA gene rearrangements are initiated after pre-TCR expression. However, in pTalpha-deficient mice, a substantial number of alphabeta+ thymocytes are still produced, in part because early TCR alpha-chain expression can rescue immature thymocytes from cell death. In this study, the nature of these TCR alpha-chains, produced and expressed in the absence of pre-TCR expression, have been analyzed. We show, by FACS analysis and sequencing of rearranged transcripts, that the TCRA repertoire is diverse in pTalpha-/- mice and that the developmental regulation of AJ segment use is maintained, yet slightly delayed around birth when compared with wild-type mice. We also found that T cell differentiation is more affected by pTalpha inactivation during late gestation than later in life. These data suggest that the pre-TCR is not functionally required for the initiation and regulation of TCRA gene rearrangement and that fetal thymocytes are more dependent than adult cells on pTalpha-derived signals for their differentiation.

Abstract
The recruitment and activation of DNA-repair mechanisms at the sites of DNA-damage after exposure of cells to genotoxic stress are poorly understood. The DNA-dependent kinase (DNA-PK) was considered to be a likely candidate for initiating these events because of the conditions required for its activation, its phosphorylation of p53 in vitro and the extreme radiosensitivity induced by its inactivation in vivo. We analyzed irradiation-induced p53-activation in SCID mice, which lack DNA-PK activity, and found that p53-dependent apoptosis and p21waf/cip1/sdi1 transcription in these animals are at least as efficient as in wild-type mice. Thus, our results show that DNA-PK is not the main sensor for genotoxic stress and is not required for p53 activation. In fact, they rather suggest that DNA-PK may play a role in p53 down-regulation.

Abstract
The X box has been shown in several assay systems to be a critical element of MHC class II gene promoters. Several X box-binding activities have been discovered in nuclear extracts from a variety of cell lines. The critical question is: which of these are responsible for mediating X box function? This report provides a further characterization of NF-X, a highly specific X box-binding activity we described previously. The cell-type distribution, structural features, and binding site characteristics of NF-X are analyzed in detail, to facilitate comparison with other reported activities. Most importantly, the functional relevance of NF-X is assessed by scanning mutagenesis, and the results indicate that this complex is indeed involved in regulating MHC class II gene expression. With these data in mind, the relationship between NF-X and RF-X, an X box-binding activity reported to be absent in patients with severe combined immunodeficiency, is discussed.
