LPS-ligation to CD14/TLR-4 on monocytes/macrophages triggers the production of IL-12-family cytokines. IL12/18 promote TH-differentiation, counteracting the TH-driven asthma. Therefore, CD14 modulation could alter the TH-differentiation and should be taken into account when studying asthma. To analyse the alteration in CD14 levels and its association with CD14 (-159 C/T) SNP (rs2569190) in Caucasian adults with stable allergic asthma, we performed a cross-sectional study (277 healthy subjects vs. 277 patients) where clinical parameters, CD14 values and the CD14 (-159 C/T) SNP were studied. Apart from typical biomarkers, we found an increment of neuron-specific enolase (NSE) in allergic asthma, probably linked to monocyte activity. Indeed, we evidenced increased monocyte numbers, but lower CD14 expression and normalised sCD14 values in patients. Moreover, we noticed an association of the T allele (P = 0.0162) and TT genotype (P = 0.0196) of the CD14 SNP with a decreased risk of allergic asthma and augmented sCD14 levels. In conclusion, monocyte CD14 expression and normalized sCD14 values were reduced in stable state asthmatics, and this could be related to the presence of an expanded CD14 monocyte subset. This study also demonstrates that the CD14 (-159 C/T) polymorphism is a risk factor for moderate-severe allergic asthma in adult Caucasians.

Standardized quality (SQ) house-dust mite (HDM) sublingual immunotherapy tablets (10,000 Japanese allergy units [JAU], equivalent to 6 SQ-HDM in Europe and the United States) are licensed for the treatment of HDM-induced allergic rhinitis (AR) without age restriction, based on 52-week administration clinical trials. There are no large-scale data on the administration of 10,000 JAU for > 1 year in actual clinical practice. To examine the safety and effectiveness of 10,000 JAU during use for up to 3 years at real-world clinical sites in Japan.

Cutaneous mastocytosis (CM) is the most common type of mastocytosis in children. The atopy frequency in these patients is typically similar to that in the general population, but a higher incidence of anaphylaxis is reported. This study aimed to evaluate the presence of allergic diseases in children diagnosed with CM and its impact on clinical manifestations.

Allergen immunotherapy (AIT) is currently the most effective immunologic form of treatment for patients with atopic allergic diseases commonly used by allergist/immunologists to reduce allergic symptoms by gradually desensitizing the immune system to specific allergens. Currently, the primary mechanism of AIT emphasizes the crucial role of immune regulation, which involves a shift from a T-helper type 2 (Th2) cell response, which promotes allergy, to a T-regulatory (Treg) cell population, which inhibits the allergic inflammatory response through the production of immunosuppressive cytokines interleukin 10 and transforming growth factor β, which play pivotal roles in suppressing the allergic reaction. In a series of previous in vitro and in vivo experiments, we have demonstrated the capacity of synthetic methylated cytosine-phosphate-guanine (CpG) oligodeoxynucleotide (ODN) moieties as well as methylated genomic DNA ODN motifs from Bifidobacterium longum subspecies infantis to activate Treg cell differentiation in contrast to the unmethylated ODN moiety, which promotes proinflammatory responses driven by Th17-mediated responses.

Nephrotic syndrome (NS) and atopic diseases are linked through shared immunological pathways, with allergic triggers often contributing to NS relapses, particularly in immunoglobulin E (IgE)-mediated pathways. Omalizumab, a humanized monoclonal antibody targeting free and cell-bound IgE, is commonly used in treating atopic diseases. We presented a pediatric case with a history of eczema, asthma, and recurrent atopic rhinitis, who first developed NS at age three, responding well to steroid therapy.

Background: The levels of biogenesis of lysosome organelles complex 1 subunit 1 (BLOC1S1) control mitochondrial and endolysosome organelle homeostasis and function. Reduced fidelity of these vacuolar organelles is increasingly being recognized as important in instigating cell-autonomous immune cell activation. We reasoned that exploring the role of BLOC1S1 in CD4 T cells may further advance our understanding of regulatory events linked to mitochondrial and/or endolysosomal function in adaptive immunity.
