Abstract
PURPOSE OF REVIEW Asthma is a chronic, inflammatory disorder of the airways caused by a complex interplay of various biologic mechanisms. Several monoclonal antibody therapies targeting interleukin (IL)-4/IL-13 and IL-5 cytokine pathways have been developed for the treatment of severe eosinophilic asthma. As individuals can display biomarkers and clinical features characteristic of several asthma phenotypes, selection of anoptimal biologic can be difficult. RECENT FINDINGS Dupilumab, a monoclonal antibody that binds to the α subunit of the IL-4 receptor (IL-4Rα) and has been approved for the treatment of adults with severe atopic dermatitis, has been shown in recent phase 3 trials to also have significant clinical benefits in the asthmatic population irrespective of baseline eosinophil counts. SUMMARY As monoclonal antibodies targeting either IL-4 or IL-13 cytokines individually have failed to demonstrate significant clinical benefits, biologics that target cytokine receptors may be more efficacious compared to those that target cytokines. Furthermore, inhibition of the IL-4/IL-13 signaling cascades may disrupt a broader Th2 inflammatory response compared to a more selective impairment of eosinophil proliferation and activity via blockage of the IL-5 pathway. Future research with independently funded, head-to-head trials of approved biologics is needed to elucidate a favorable therapeutic option.

Abstract
Current asthma treatments are effective for the majority of patients with mild-to-moderate disease. However, in those with more severe refractory asthma, agents other than inhaled corticosteroids and beta-agonists are needed both to better manage this group of patients and to avoid the side effects of high-dose corticosteroids and the social and personal hardship endured. Several biological pathways have been targeted over the last 20 years, and this research has resulted in pharmacological approaches to attempt to better treat patients with severe refractory asthma. The flagship of the biologics, the anti-IgE monoclonal antibody, omalizumab, has proven efficacious in selected subgroups of asthma patients. Tailoring asthma treatments to suit specific subtypes of asthma patients is in keeping with ideals of personalized medicine. Research in the complex interplay of allergens, epithelial host defenses, cytokines, and innate and adaptive immunity interactions has allowed better understanding of the mechanics of allergy and inflammation in asthma. As a result, new biologic treatments have been developed that target several different phenotypes and endotypes in asthma. As knowledge of the efficacy of these biological agents in asthma emerges, as well as the type of patients in whom they are most beneficial, the movement toward personalized asthma treatment will follow.

Abstract
Asthma is a multifactorial disease that is influenced by the interaction of genetic and environmental factors. Because of its complex nature, there is no cure for asthma currently. Instead, reliever and controller medications are used to treat asthma. Unfortunately, conventional treatments do not work in some severe cases of asthma. In addition, there may be adverse, systemic effects of long-term treatment with high-dose inhaled corticosteroids (ICSs) as a controller medication. Therefore, we attempted to develop a novel combination therapy for asthma. Our regimen included dexamethasone as a controller medication and vitamin D binding protein (VDBP) small interfering RNA (siRNA) as a novel target therapeutic. The dexamethasone moiety of DEXA-PEI (dexamethasone-conjugated polyethylenimine) was used as an ICS, combined with anti-VDBP treatment via delivery of VDBP siRNA, using DEXA-PEI as a siRNA carrier molecule. Treatment with DEXA-PEI/VDBP siRNA effectively reduced the ovalbumin sensitization/challenge-induced enhancement of airway inflammation, goblet cell hyperplasia and expression of interleukin (IL)-4, IL-13 and CCL11. These findings suggest that the DEXA-PEI/VDBP siRNA can be developed as a potent asthma therapeutic by dose-reducing ICSs and using a multitarget therapeutic method.

Abstract
Airway mucus hypersecretion is a significant clinical and pathological feature of chronic inflammatory airway diseases. Its clinical presentations include recurrent coughing and phlegm. Airway mucus is closely associated with the occurrence, development and prognosis of chronic inflammatory airway diseases and critically affects the lung function, quality of life, hospitalization rate and mortality of patients with chronic inflammatory airway diseases. Therefore, expectorant therapies targeting the potential mechanisms of mucus hypersecretion have been the focus of numerous studies. Conventional expectorants are mainly mucoactive medicines, including nausea-stimulating expectorants, mucolytics, mucokinetics, and proteases and nucleases. In addition, certain traditional Chinese herbal medicines and non-mucoactive agents, including muscarinic acetylcholine receptor antagonists, corticosteroids, leukotriene receptor antagonists and macrolide antibiotics, have also shown expectorant effects. Several novel medicines for expectorant therapy have emerged, including cholesterol-lowering statins, epidermal growth factor receptor tyrosine kinase inhibitors, phosphodiesterase-4 inhibitors, stanozolol, surfactants, flavonoids, tachykinin receptor antagonists, protease inhibitors, cytokine antagonists and purinergic agonists. With the increasing number of multidisciplinary studies, the effectiveness of expectorant therapy for the treatment of chronic inflammatory airway diseases has been confirmed. Therefore, the development of novel expectorants and the standardization of expectorant therapy are the direction and focus of future studies, thus benefiting patients who have a chronic inflammatory airway disease.

Abstract
SCOPE It has been suggested that n-3 PUFA can be used as a preventive or therapeutic strategy to control allergic asthma. But little is known about the exact mechanisms by which n-3 PUFA modulates it. Here, the effects of elevated n-3 PUFA on ovalbumin (OVA) induced airway inflammation were investigated using Fat-1 transgenic mice that can convert n-6 PUFA to n-3 PUFA endogenously. METHODS AND RESULTS First, we tested whether Fat-1 expression modulates CD4⁺ T-cell activation, proliferation, and differentiation in vitro and found that the Fat-1 expression attenuated all of these CD4⁺ T-cell responses by suppression of T-cell receptor mediated signaling and cytokine-mediated phosphorylation of STATs. When the Fat-1 mice were sensitized and challenged with the OVA, they showed a significant decrease in the recruitment of inflammatory cells into airway, the production of Th2 cytokines, eotaxin, and mucin in the lung, and the concentration of OVA-specific IgE in the serum. Furthermore, the differentiation of CD4⁺ T cells into Th2 was also decreased in the spleen of Fat-1 mice. CONCLUSION Our results showed that an elevated level of n-3 PUFA was effective in preventing allergic airway inflammation by modulating the activation and differentiation of CD4⁺ T cells in Fat-1 mice.

Abstract
Siglecs (sialic acid immunoglobulin-like lectins) are members of the immunoglobulin gene family that contain sialoside binding N-terminal domains. They are cell surface proteins found predominantly on cells of the immune system. Among them, Siglec-8 is uniquely expressed by human eosinophils and mast cells, as well as basophils. Engaging this structure with antibodies or glycan ligands results in apoptosis in human eosinophils and inhibition of release of preformed and newly generated mediators from human mast cells without affecting their survival. Pro-apoptotic effects are also seen when its closest functional paralog, Siglec-F, on mouse eosinophils is similarly engaged in vitro, and beneficial effects are observed after administration of Siglec-F antibody using models of eosinophilic pulmonary and gastrointestinal inflammation in vivo. Siglec-8 targeting may thus provide a means to specifically inhibit or deplete these cell types. Cell-directed therapies are increasingly sought after by the pharmaceutical industry for their potential to reduce side effects and increase safety. The challenge is to identify suitable targets on the cell type of interest, and selectively deliver a therapeutic agent. By targeting Siglec-8, monoclonal antibodies and glycan ligand-conjugated nanoparticles may be ideally suited for treatment of eosinophil and mast cell-related diseases, such as asthma, chronic rhinosinusitis, chronic urticaria, hypereosinophilic syndromes, mast cell and eosinophil malignancies and eosinophilic gastrointestinal disorders.
