Abstract
Acute myeloid leukemia (AML) is characterized by an increased proliferation and loss of differentiation of hematopoietic myeloid progenitors or precursors. Studies performed in AML-affected patients revealed a T cell deficiency characterized by a reduced thymic output and peripheral functional abnormalities. To assess for the thymus function during AML, we used an AML mouse model and showed a drastic thymic atrophy. We observed a massive loss among double (CD4+CD8+- DP) and single positive (CD4+/8+- SP) thymocytes. We assessed for the expression of different actors of cell death signalling pathways by RT-qPCR or Western blotting. When comparing leukemic to control mice, there was a significant increase in the expression of Mlkl gene, phosphorylated MLKL and RIPK3 proteins, and tumor necrosis factor (TNF)-alpha receptors 1 on DP and SP thymocytes. These findings revealed a necroptosis cell death which was also observed in vitro when using cultured wild-type thymocytes and recombinant TNF-alpha protein. Thus, we demonstrated that TNF-alpha plays a deleterious role in thymic function during AML by contributing to extensive thymocytes' death.

Abstract
The thymus is a vital organ of the immune system that plays an essential role in thymocyte development and maturation. Thymic atrophy occurs with age (physiological thymic atrophy) or as a result of viral, bacterial, parasitic or fungal infection (pathological thymic atrophy). Thymic atrophy directly results in loss of thymocytes and/or destruction of the thymic architecture, and indirectly leads to a decrease in naïve T cells and limited T cell receptor diversity. Thus, it is important to recognize the causes and mechanisms that induce thymic atrophy. In this review, we highlight current progress in infection-associated pathogenic thymic atrophy and discuss its possible mechanisms. In addition, we discuss whether extracellular vesicles/exosomes could be potential carriers of pathogenic substances to the thymus, and potential drugs for the treatment of thymic atrophy. Having acknowledged that most current research is limited to serological aspects, we look forward to the possibility of extending future work regarding the impact of neural modulation on thymic atrophy.

Abstract
The infection of bacterial organisms generally causes cell death to facilitate microbial invasion and immune escape, both of which are involved in the pathogenesis of infectious diseases. In addition to the intercellular infectious processes, pathogen-produced/secreted enterotoxins (mostly exotoxins) are the major weapons that kill host cells and cause diseases by inducing different types of cell death, particularly apoptosis and necrosis. Blocking these enterotoxins with synthetic drugs and vaccines is important for treating patients with infectious diseases. Studies of enterotoxin-induced apoptotic and necrotic mechanisms have helped us to create efficient strategies to use against these well-characterized cytopathic toxins. In this article, we review the induction of the different types of cell death from various bacterial enterotoxins, such as staphylococcal enterotoxin B, staphylococcal alpha-toxin, Panton-Valentine leukocidin, alpha-hemolysin of Escherichia coli, Shiga toxins, cytotoxic necrotizing factor 1, heat-labile enterotoxins, and the cholera toxin, Vibrio cholerae. In addition, necrosis caused by pore-forming toxins, apoptotic signaling through cross-talk pathways involving mitochondrial damage, endoplasmic reticulum stress, and lysosomal injury is discussed.

Abstract
Cotesia vestalis is an endoparasitoid of larval stages of Plutella xylostella, the diamondback moth. For successful parasitization, this parasitoid injects a polydnavirus into its host during oviposition. Here we isolated two genes, which we named CvBV1 and CvBV2. CvBV1 was located on segment CvBV-S5 with a size of 790 bp, while CvBV2 was located on segment CvBV-S51 with a size of 459 bp. A gene copy of CvBV2 was found on segment CvBV-S48, which we name CvBV2’. Gene duplication occurred in both genes, tandem gene duplication for CvBV1 and segmental duplication for CvBV2. Gene transcripts of the two genes were detected in hosts as early as 0.5 h post-parasitization (p.p.) and continued to be detected for six days, and tissue-specific expression patterns showed that they could be detected in the haemolymph and brain at 2 h p.p., suggesting that they could participate in early protection of parasitoid eggs from host cellular encapsulation.

Abstract
The delta-opioid receptor-1 (DOR-1) as well as delta-opioid enkephalin peptides are expressed during maturation of T cells, although the functional significance of their expression remains unclear. Based on results which show that the administration of the highly selective delta-opioid agonist D-Pen2, D-Pen5]enkephalin (DPDPE) induces an altered pattern of T-cell differentiation in fetal thymic organ culture (FTOC), we hypothesized that DOR-1 is involved in the negative selection process. Our results show that superantigen-induced clonal deletion is promoted by DPDPE and significantly impaired in DOR-1-deficient mice. These results suggest that delta-opioids may play a homeostatic role in the negative selection process during T-cell development.

Abstract
Currently available murine staphylococcal enterotoxin B (SEB) shock models require pretreatment with various agents to increase mouse sensitivity to SEB. This study was performed to show that C3H/HeJ mice are highly susceptible to intranasal SEB inoculation, which caused toxic shock without using pretreatment agents. For this purpose, mice were injected intranasally with different doses of SEB and observed for up to 1 month. The median lethal dose of SEB was determined using the probit procedure. Tissue samples were taken at different time points for histopathological examination. The LD(50) was found at 1.6 microg/g (95% fiducial limit (f.l.) 0.7 to 2.2), the LD(80) at 2.7 microg/g (95% f.l. 1.9 to 4.0) and the LD(90) at 3.6 microg/g (95% f.l. 2.7 to 6.4). Histopathologic examination revealed pulmonary edema and bronchopneumonia. Mucosal-associated lymphoid tissue first became activated, followed by increasing lymphocyte apoptosis and depletion. In the liver there were intralobular and portal inflammatory foci with increasing lymphocyte apoptosis and degenerative necrosis. The splenic white pulp was characterized by early activation and subsequent depletion of lymphoid follicle germinal centers. The thymus initially was activated, followed by increasing apoptosis and migration of lymphoid cells from the cortex to the medulla. The pathological features detected in the mice were similar to those of rhesus monkeys treated with SEB aerosol challenge.

Abstract
Macrophage-derived chemokine (MDC) is a potent chemoattractant for antigen-specific T lymphocytes. We hypothesized that Adenovirus- (Ad-) transduced dendritic cells (DCs) overexpressing MDC would enhance the T cell-mediated humoral immune response specific for antigens presented by the DC. We challenged two strains of mice with lethal Pseudomonas aeruginosa infection 3 weeks after immunization with AdMDC-modified DCs pulsed with heat-killed P. aeruginosa. MDC-expressing DCs specifically attracted T lymphocytes and preserved typical DC surface phenotypes without growth factors in vitro. Mice immunized with AdMDC/Pseudomonas/DCs developed high levels of serum anti-Pseudomonas Ab's and were protected from a lethal respiratory challenge with Pseudomonas. The in vivo protective immunity required CD4(+) T cells, B cells, and IL-4, but not CD8(+) T cells and IL-12. AdMDC/DCs pulsed with Pseudomonas yielded significant but not absolute cross-protection against different strains of P. aeruginosa. Pseudomonas-pulsed AdMDC/DCs protected mice from Pseudomonas but not Escherichia coli and vice versa; this microbe-specific protection correlated with microbe-specific induction of CD4(+) T cell proliferation and IL-4 secretion. Based on these observations, AdMDC-modified DCs pulsed with a killed bacteria may be a useful approach to vaccination against infectious disorders.

Abstract
Exposure to bacterial superantigens leads to the induction of a subsequent state of immune hyporesponsiveness. Using a transwell coculture system, a previous report demonstrated that splenocytes from staphylococcal enterotoxin B (SEB)-injected BALB/c mice secreted soluble mediators to suppress the proliferative response of naive syngeneic splenocytes to SEB stimulation. We show in the present study that, in contrast to the suppressive effect induced by SEB in BALB/c (H-2(d) haplotype), MRL(+/+), and MRL-lpr/lpr (H-2(k)) mice, SEB-primed splenocytes from I-E(-) strains such as B6, B10, A. BY (H-2(b)), and A.SW (H-2(s)) mice failed to inhibit the CD25 expression and the proliferative activity of their syngeneic naive responder splenocytes. Further results revealed that the SEB-primed cells from BALB/c, but not B6, mice inhibited the CD25 expression and proliferation of naive responder cells from either BALB/c or B6 mice, indicating the critical regulatory role of the effector cells. Unlike SEB, staphylococcal enterotoxin A induced profound suppression in both BALB/c and B6 mice. Moreover, the suppressive competence of SEB-primed splenocytes was diminished in CD28-deficient BALB/c mice. Taken together, our results indicate that when SEB is used as a stimulator in vivo, both the I-E molecule and CD28 costimulation are required for the induction of regulatory cells bearing suppressive activity.
