    Abstract Allergen-specific Immunotherapy (AIT) is the main therapeutic strategy to control and treat allergic disorders. Intranasal Immunotherapy (INIT) was introduced as a needle-free, noninvasive, and efficient approach among various routes of allergen administration. Since direct exposure of nasal mucosa to allergen extracts could induce local and systemic reactions, recent studies focus on establishing novel formulations using various delivery systems and adjuvants to improve INIT efficacy. This review categorizes and describes natural and synthetic micro/nanoparticles such as chitosan, PLGA, liposome, exosome, and nano-emulation droplets used as delivery systems or immunomodulatory and immune-regulatory agents. Also, multiple microbial agents, including probiotics, mycobacterial and viral components, TLR ligands, and biologic agents, i.e., antibody fragments, recombinant cytokines, vitamin A, and pulsed dendritic cells (DCs), are other platforms that are discussed. In addition, future perspectives and proposed strategies to help INIT were provided.

    Abstract Gold nanoparticles (GNPs) have been recently applied for various diagnostic and therapeutic purposes. The unique properties of these nanoparticles (NPs), such as relative ease of synthesis in various sizes, shapes and charges, stability, high drug-loading capacity and relative availability for modification accompanied by non-cytotoxicity and biocompatibility, make them an ideal field of research in bio-nanotechnology. Moreover, their potential to alleviate various inflammatory factors, nitrite species, and reactive oxygen production and the capacity to deliver therapeutic agents has attracted attention for further studies in inflammatory and autoimmune disorders. Furthermore, the characteristics of GNPs and surface modification can modulate their toxicity, biodistribution, biocompatibility, and effects. This review discusses in vitro and in vivo effects of GNPs and their functionalized forms in managing various autoimmune disorders (Ads) such as rheumatoid arthritis, type 1 diabetes, and multiple sclerosis.

    Abstract Progressive degeneration and dysfunction of the nervous system because of oxidative stress, aggregations of misfolded proteins, and neuroinflammation are the key pathological features of neurodegenerative diseases. Alzheimer's disease is a chronic neurodegenerative disorder driven by uncontrolled extracellular deposition of β-amyloid (Aβ) in the amyloid plaques and intracellular accumulation of hyperphosphorylated tau protein. Curcumin is a hydrophobic polyphenol with noticeable neuroprotective and anti-inflammatory effects that can cross the blood-brain barrier. Therefore, it is widely studied for the alleviation of inflammatory and neurological disorders. However, the clinical application of curcumin is limited due to its low aqueous solubility and bioavailability. Recently, nano-based curcumin delivery systems are developed to overcome these limitations effectively. This review article discusses the effects and potential mechanisms of curcumin-loaded PLGA nanoparticles in Alzheimer's disease.

    Abstract The expansion of myeloid-derived suppressor cells (MDSCs), known as heterogeneous population of immature myeloid cells, is enhanced during several pathological conditions such as inflammatory or viral respiratory infections. It seems that the way MDSCs behave in infection depends on the type and the virulence mechanisms of the invader pathogen, the disease stage, and the infection-related pathology. Increasing evidence showing that in correlation with the severity of the disease, MDSCs are accumulated in COVID-19 patients, in particular in those at severe stages of the disease or ICU patients, contributing to pathogenesis of SARS-CoV2 infection. Based on the involved subsets, MDSCs delay the clearance of the virus through inhibiting T-cell proliferation and responses by employing various mechanisms such as inducing the secretion of anti-inflammatory cytokines, inducible nitric oxide synthase (iNOS)-mediated hampering of IFN-γ production, or forcing arginine shortage. While the immunosuppressive characteristic of MDSCs may help to preserve the tissue homeostasis and prevent hyperinflammation at early stages of the infection, hampering of efficient immune responses proved to exert significant pathogenic effects on severe forms of COVID-19, suggesting the targeting of MDSCs as a potential intervention to reactivate T-cell immunity and thereby prevent the infection from developing into severe stages of the disease. This review tried to compile evidence on the roles of different subsets of MDSCs during viral respiratory infections, which is far from being totally understood, and introduce the promising potential of MDSCs for developing novel diagnostic and therapeutic approaches, especially against COVID-19 disease.

    Abstract Allergen-specific sublingual immunotherapy (SLIT), a safe and efficient route for treating type I hypersensitivity disorders, requires high doses of allergens. SLIT is generally performed without adjuvants and delivery systems. Therefore, allergen formulation with appropriate presentation platforms results in improved allergen availability, targeting the immune cells, inducing regulatory immune responses, and enhancing immunotherapy's efficacy while decreasing the dose of the allergen. In this review, we discuss the adjuvants and delivery systems that have been applied as allergen-presentation platforms for SLIT. These adjuvants include TLRs ligands, 1α, 25-dihydroxy vitamin D3, galectin-9, probiotic and bacterial components that provoke allergen-specific helper type-1 T lymphocytes (TH1), and regulatory T cells (Tregs). Another approach is encapsulation or adsorption of the allergens into a particulate vector system to facilitate allergen capture by tolerogenic dendritic cells. Also, we proposed strategies to increasing the efficacy of SLIT via new immunopotentiators and carrier systems in the future.

    Abstract Background: Determination of foetus rhesus blood group at risk of hemolytic disease has potential application for early non-invasive prenatal testing (NIPT). There are several challenges in developing NIPT rhesus blood group genotyping assays by using cell-free foetal DNA (cff-DNA) in plasma of RhD-negative pregnant women. So, the aim of this study was optimization of Real-time PCR assay for NIPT rhesus genotyping and development of Bi-allelic short insertion/deletion polymorphisms (INDELs) as internal control to optimise and validate rhesus genotyping based on Real-time PCR to avoid false or negative results.
    Material and methods: NIPT Rhesus genotyping including RHD (exon 7), RHCc, and RHEe genes were performed by TaqMan Real-time PCR on 104 maternal samples at different gestation ages (12 to ≥40 weeks) from 51 alloimmunized pregnant women. The sensitivity protocol was confirmed with standard DNA samples. Eight selected INDELs were designed and used to detectable cff-DNA in maternal plasma. INDELs frequency and inheritance were determined on 6 family and 61 unrelated individuals. Finally, multiplex Real-time PCR was performed for each sample with INDELs pairs and Rh probes.
    Results: The results showed 100% accuracy rhesus typing for RHD, RHC and RHE assays and 95.7% accuracy for RHc. Also, eight selected INDELs as internal control for NIPT were 100% concordance for typed samples.
    Conclusion: The Real-time PCR assay is a suitable method with high sensitivity and specificity for rhesus typing as NIPT for prediction of hemolytic disease in foetuses. The INDELs described here are suitable internal control for confirmation of NIPT on cff-DNA.

    Abstract Introduction and purpose: One of the most valuable and widely used methods in screening and evaluating respiratory diseases and diagnosing lung disorders is spirometry and comparing its value with standard references. Therefore, the present study aimed to measure and compare spirometric values among adults in Esfarayen (northeastern Iran). Methods: In this cross-sectional study, demographic, anthropometric, and spirometry data (based on American Thoracic Society criteria) were obtained from 317 normal adults in the summer of 2019. Thereafter, the Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75), and peak expiratory flow (PEF) values in Iranian adult population were compared with predictions from Economic Community for Coal and Steel ( ECCS), Knudson, Morris, and Pereira standardized references Data was analyzed in SPSS (version 18) using descriptive and analytical statistics (Kolmogorov-Smirnov, Pearson correlation and Paired sample t-test). Results: The mean scores of age and Body Mass Index (BMI) of subjects were reported as 29.63±0.38 years and 23.87±0.19 kg/m2, respectively. Statistical analysis demonstrated that the measured values of FVC, FEV1، FEF25-75, and PEF were significantly correlated with Knudson, Morris, ECCS, and Pereira references (P<0.05). Conclusion: The comparison of the measured spirometric values with the international standards revealed that the Morris standard had a very high correlation with all the measured spirometric values. Therefore, this standard was identified as a suitable (consistent) and applicable reference in the study population.

    Abstract Inflammasomes are important intracellular multiprotein signaling complexes that modulate the activation of caspase-1 and induce levels of the proinflammatory cytokines interleukin-1β (IL-1β) and IL-18 in response to pathogenic microorganisms and molecules that originated from host proteins. Inflammasomes play contradictory roles in the development of inflammation-induced cancers. Based on several findings, inflammasomes can initiate and promote carcinogenesis. On the contrary, inflammasomes also exhibit anticancer effects by triggering pyroptosis and immunoregulatory functions. Herein, we review extant studies delving into different functions of inflammasomes in colorectal cancer development.

    Abstract Recently, the main goal of many allergy epicutaneous immunotherapy (EPIT) studies is to enhance the allergen delivery through the intact skin. Therefore, applying new strategies for tackling this issue are inevitable. For this purpose, ten groups of Che a 2-sensitized BALB/c mice were epicutaneously treated for a 6-week period with the rChe a 2-GNPs-Aptamer, rChe a 2-GNPs-Aptamer + skin-penetrating peptides (SPPs), rChe a 2-GNPs, rChe a 2, GNPs, and PBS. Afterward, the serum IgE and IFN-γ, TGF-β, IL-10, IL-4, IL-17a cytokine production, NALF analysis, and lung/nasal histological examinations were performed. The present study results demonstrate that, EPIT in aptamer treated groups had a significant increase of IFN-γ, TGF-β, and IL-10 concentrations and a significant decrease of IgE, IL-4, and IL-17a concentrations as well as NALF infiltrated immune cell count compared to the non-targeted ones. In addition, SPPs led to more significant improvement of immunoregulatory parameters, especially IL-10 cytokine. Accordingly, the targeted-GNPs with DC-specific aptamers could act as an efficient approach for the improvement of EPIT efficacy compared to the free allergen. Moreover, the application of SPPs might be considered as a useful tool in achieving a successful EPIT with lower doses of allergen at a shorter duration of the treatment.
