BACKGROUND: Allergic asthma is a degenerative atopic disease caused by allergic or hypersensitivity type-1. More than 50% of people with allergic asthma are caused by the presence of house dust mites (HDMs) allergens.METHODS: The cellular immunity response was evaluated through a peripheral blood mononuclear cell (PBMC) culture isolated from blood, using the ficoll gradient technique. Subjects were atopic asthma groups and non-atopic asthma groups. PBMC from each subject cultured was stimulated with HDMs allergen, then incubated in a CO2 5% incubator, 37o C for 72 hours. With the multiplex assay method, interferon (IFN)-γ, interleukin (IL)-13 and IL-10 were measured, meanwhile indoleamine 2,3-dioxygenase level (IDO) was measured by the enzyme-linked immunosorbent assay (ELISA) sandwich methods.RESULTS: The IFN-γ production in the supernatant of PBMC cultures was stimulated by phytohemagglutinin (PHA), Roswell Park Memorial Institute (RPMI) medium and allergens. The IFN-γ production in allergen-stimulated supernatants showed higher level of IFN-γ in the nonatopic group (4,681,455±3,434,851) than atopic group (4,363,300±2,067,941) even though it was not statistically significant (p=0.078). There were no differences between the mean of IL-13 production in atopic asthma group and non-atopic group. The IL-10 production in allergenstimulated supernatants was shown to be higher in nonatopic group and were statistically significantly different (p=0.015). The IDO production in allergen-stimulated supernatants was shown to be higher in the non-atopic group (272,231±269,564) than in the actopic group (13,273±400), and it was significantly different (p=0.007).CONCLUSION: Cellular immune profile of subjects with allergic asthma to Dermatophagoides pterronyssinus (Der p) is characterized by a type-2 inflammatory response that is dominant compared to type-1 inflammation (higher IL-13 ratio compared to IFN-γ) and to the role of anti-inflammation (higher IL-13 ratio compared to IL-10). The decline in IDO production in allergic asthma subjects to Der p is thought to be related to the low cellular immune response in expressing IFN-γ compared to IL-13.KEYWORDS: interleukin-13, interleukin-10, IDO, PBMC, asthma

Abstract Background Polyvalent Mechanical Bacterial Lysate (PMBL®) contains antigens of bacteria responsible for respiratory infections. PMBL® has been proven to reduce the number of respiratory infections, and in its use, immunological benefits have been seen in allergic patients. PMBL® activates both innate and specific immune responses. The lysate induces dendritic cells, T and B lymphocytes and IgA secretion, as well as the production of antibodies directed against administered bacterial antigens. Moreover, it increases the response against other bacteria and viruses. The immunologic mechanism of lysate’s action is not yet clearly determined. The objective of this study was to assess the effect of PMBL® on T cells in children with allergic asthma. Methods This study was a part of the EOLIA study. Herein, 49 children with allergic asthma and house dust mites allergy were included: 21 in PMBL® and 28 in the Placebo group, both, drug and placebo were administered sublingually. The tests were done at baseline and 12 weeks after the last tablet intake. The lymphocytes CD45+, lymphocytes T CD3+, CD3+CD25+, CD3+CD69+, Th CD3+CD4+, CD4+CD25+, CD4+CD25+ high, CD4+CD69+, Treg CD4+CD25+FOXP3, Tc CD3+CD8+, CD8+CD25+, CD8+CD69+, NK-like T CD3+CD16+CD56+ and NK cells CD3−CD16+CD56+ were described. Results At baseline, no significant differences between groups relative to blood count cells were observed, except for eosinophils. After 12 weeks, we observed an increase of T lymphocytes count. In addition, CD4+CD25+FOXP3+, CD8+ and CD3−CD16+CD56+ and (insignificantly) Th count increased. However, CD69+ and CD25+ subset of CD3+ significantly decreased. Conclusions The EOLIA study demonstrated that PMBL® administration 10 days per month for 3 months changed the panel of T lymphocytes.

ABSTRACT We previously demonstrated that the principal component of capsular material of Cryptococcus neoformans, glucuronoxylomannan (GXM), induces interleukin-10 (IL-10) secretion from human monocytes. Here we report that encapsulation of the yeast with GXM is able to down-regulate interleukin-12 (IL-12) production by monocytes that would normally occur in the absence of encapsulation. This phenomenon appeared to be the result of inhibition of the phagocytic process by encapsulation with GXM as well as of negative signals such as IL-10 secretion produced by interaction of GXM with leukocytes. Decreased secretion of IL-12 correlated with decreased release of gamma interferon (IFN-γ) from T cells, suggesting a role for encapsulation with GXM in hindering a T helper type 1 (Th1) response. This is supported by the ability of encapsulation with GXM to limit increased expression of B7-1 costimulatory molecules that otherwise might limit IL-10 secretion. Endogenous IL-10 played a critical role in modulatory activity associated with encapsulation with GXM. Blocking IL-10 with monoclonal antibody to IL-10 resulted in increased (i) IL-12 secretion, (ii) IFN-γ release from T cells, and (iii) killing of C. neoformans by monocytes. These results suggest that encapsulation with GXM limits development of a protective Th1-type response, an inhibitory process in which IL-10 plays a critical role. Scavengers of GXM and/or IL-10 could be useful in a protective Th1-type response in patients with cryptococcosis.

BACKGROUND: Cardiovascular disease (CVD) is one the cause of mortality in patients with type 1 diabetes (T1D). The development of CVD is mainly triggered by atherosclerosis, which is associated with the inflammatory process. AIM: The current study was aimed to investigate the association of Vitamin D level and premature atherosclerosis in adolescents with T1D, mainly through the regulation of various cytokines (interferon-γ [IFN-γ], IL-17, interleukin-10 [IL-10], and transforming growth factor-β1 [TGF-β1]). METHODS: This study was designed as a cross-sectional study involving 40 T1D and 40 healthy control who came to the outpatient clinic, Saiful Anwar Hospital, Malang, Indonesia, within the study period (January 2019-July 2019). RESULTS: Our data demonstrated that the IFN-γ and IL-17 levels were significantly higher (p < 0.001), whereas the TGF-β1 and IL-10 levels were significantly lower (p < 0.001) in T1D group compared with control. Furthermore, T1D also has higher carotid intima-media thickness (cIMT) value and lower flow-mediated dilatation (FMD) value compared to the control group (p < 0.001). Level of 25(OH)D3 was strongly associated with reduced cIMT and elevated FMD (p < 0.005). The direct effect of 25(OH)D3 on cIMT and FMD was higher than the indirect effect of Vitamin D through TGF-β1, IL-10, IL-17, and IFN-γ. The cutoff value of 25(OH)D3 levels for the risk of atherosclerosis was 12.8 ng/dL (sensitivity 85.7% and specificity 86.7%). CONCLUSION: The level of Vitamin D in the T1D group was significantly lower than those in healthy children and Vitamin D deficiency substantially influences the formation of premature atherosclerosis.

Abstract Background: Studies have indicated that allergens such as house dust mites (HDM) in the environment could induce allergic asthma. Ferroptosis is a newly discovered regulatory cell death characterized by aberrant lipid peroxidation and accumulation of reactive oxygen species (ROS) in cells. However, whether ferroptosis participates in the pathological progress of asthma remains to be elucidated. In this study, we used a HDM-induced mouse asthma model to determine the effect of HDM exposure on allergic asthma and the underlying mechanisms. Methods: Female BALB/c mice were intranasally exposed to HDM to induce allergic asthma. Airway hyperresponsiveness (AHR), lung inflammation and mucus secretion, IgE and cytokine levels as well as inflammatory cell counts in bronchalveolar lavage fluid (BALF) were investigated. In addition, the morphological changes of mitochondria, ROS, glutathione (GSH) levels and changes in ferroptosis pathway proteins in the lung were also determined. Results: HDM exposure increased AHR significantly, and enhanced inflammatory cell infiltration and mucus secretion around the airways. Furthermore, elevated IgE level in BALF, lung eosinophilia, and a concomitant increase in IL-13 and IL-5 in BALF were observed. HDM inhalation increased ROS and decreased GSH level in the lung. HDM inhalation induced dysmorphic small mitochondria with decreased crista, as well as condensed, ruptured outer membranes. Western blot analysis demonstrated that activity of glutathione peroxidase 4 (GPX4) and catalytic subunit solute carrier family 7 member 11 (SLC7A11) decreased significantly, and protein expression of acyl-CoA synthetase long-chain family member 4 (ACSL4) and 15 Lipoxygenase 1 (15-LO1) upregulated prominently compared with mice in normal control group. Conclusions: These in all indicated that the AHR, airway inflammation, lipid peroxidation and ROS level increased in HDM-induced asthma, and HDM inhalation caused ferroptosis in the lungs, which helped to form a better understanding of the pathogenesis of allergic asthma and targeted treatment strategies.

AbstractEvidence regarding asthma’s impact on children’s daily lives is limited. This prospective and cross-sectional, observational, multicenter study assessed school/work and activity impairment in children and adolescents with allergic asthma and their caregivers and allergen immunotherapy (AIT) effects. Included patients were schooled children and adolescents (5 to 17 years) with allergic asthma due to house dust mites (HDM). Impairment of school/work (i.e., absenteeism and presenteeism) and activity was measured in patients and their caregivers using the Work Productivity Impairment Questionnaire plus Classroom Impairment Questions: Allergy Specific (WPAI + CIQ:AS). HDM allergic patients with school impairment received subcutaneous AIT with a MicroCrystalline Tyrosine-associated allergoid. WPAI + CIQ:AS and effectiveness variables were compared between baseline and 1-year post-AIT. Of the 113 patients included, 59 (52.2%) and 51 (45.1%) showed school and activity impairment, respectively, missing a mean (SD) of 37.6 (24.4) % and 42.6 (25.6) % of school and activity time, respectively. Twenty-six (23%) caregivers reported activity impairment and, of the 79 (69.9%) employed, 30 (38%) reported work impairment. Of the 65 patients with school/activities impairment, 41 (63.1%) received AIT, of which 21 (51.2%) completed 1 year of treatment. Effectiveness variables and WPAI + CIQ:AS significantly improved: Mean (SD) school impairment decreased from 39.7 (26.7) to 2.1 (7.1) % (p < 0.001) and activity impairment from 46.2 (34.6) to 1.4 (3.6) % (p < 0.001).Conclusion: Allergic asthma due to HDMs results in school/work and activity impairment in children and adolescents and their caregivers. One year of AIT provided clinical benefits and reduced school and activity impairment. What is Known:• Allergic asthma impairs children’s school performance and daily activities.• Allergen immunotherapy modifies allergic disease course and ameliorates its symptoms. What is New:• Asthma symptoms due to allergy to house dust mites impair children’s school attendance and productivity and daily activity and their caregivers’ work performance and daily lives.• Allergen immunotherapy with a house dust mite MicroCrystalline Tyrosine (MCT)-associated allergoid seems to provide clinical benefits, associated with decreased school and activity impairment, supporting it as an effective treatment option.

Bronchial Allergen Challenge

House dust mites (HDMs) are the allergenic sources most frequently involved in airway allergy. Nevertheless, not every sensitized patient develops respiratory symptoms upon exposure to HDM, and there is a clinical need to differentiate allergic asthmatics (AAs) from atopic non-allergic asthmatics with HDM sensitization. This differentiation sometimes requires in vivo provocations like the bronchial allergen challenge (BAC). Interestingly, recent data demonstrate that non-atopic patients with asthma can also develop positive BAC results. This novel phenotype has been termed local allergic asthma (LAA). The interest in identifying the allergic triggers of asthma resides in the possibility of administering allergen immunotherapy (AIT). AIT is a disease-modifying intervention, the clinical benefit of which persists after therapy discontinuation. Recently, new modalities of sublingual tablets of HDM immunotherapy registered as pharmaceutical products (HDM-SLIT tablets) have become commercially available. HDM-SLIT tablets have demonstrated a robust effect over critical asthma parameters (dose of inhaled corticosteroids, exacerbations, and safety), thus being recommended by international guidelines for patients with HDM-driven AA. In this review, we will summarize the current knowledge on the phenotype and endotype of HDM-driven AA, and LAA, address the difficulties for BAC implementation in the clinic, and discuss the effects of AIT in AA and LAA.

It is a high priority to develop a simple and effective delivery method for a cross-protective influenza vaccine. We investigated skin immunization by microneedle (MN) patch with human influenza split vaccine and virus-like particles containing heterologous M2 extracellular (M2e) domains (M2e5x virus-like particles (VLP)) as a cross-protective influenza vaccine candidate. Co-delivery of influenza split vaccine and M2e5x VLP to the skin by MN patch was found to confer effective protection against heterosubtypic influenza virus by preventing weight loss and reducing lung viral loads. Compared to intramuscular immunization, MN-based delivery of combined split vaccine and M2e5x VLPs shaped cellular immune responses toward T helper type 1 responses increasing IgG2a isotype antibodies as well as IFN-γ producing cells in mucosal and systemic sites. This study provides evidence that potential immunological and logistic benefits of M2e5x VLP with human influenza split vaccine delivered by MN patch can be used to develop an easy-to-administer cross-protective influenza vaccine.
