Antibodies targeting the interleukin–5 signaling pathway used as add-on therapy for patients with severe eosinophilic asthma: a review of the mechanism of action, efficacy and safety of the subcutaneously administered agents, mepolizumab and benralizumab.
Introduction: Since the discovery of eosinophils in the sputum of patients with asthma, several studies have offered evidence on their important role in the pathology and severity of asthma. blood eosinophils, is a useful biomarker for selection of therapy in patients with severe asthma. IL-5 plays a crucial role in the maturation, activation, recruitment and survival of eosinophils and is an important therapeutic target for patients with uncontrolled severe eosinophilic asthma.
Areas Covered: This review focuses on the similarities and differences in the mechanism of action, efficacy and safety, the two agents subcutaneous (SC), an anti-interleukin (IL) -5 mepolizumab monoclonal antibody and IL-5 receptor-α (IL-5Rα) -directed benralizumab cytolytic monoclonal antibody.
All information is used collected from PubMed using keywords like severe asthma, eosinophils, IL5, airway inflammation, asthma exacerbations, mepolizumab, benralizumab, anti-IL5, and anti-IL5R either as a single term or in some combinations.Expert Opinion: mepolizumab and benralizumab both promising for the treatment of severe eosinophilic asthma triggers asthma control and exacerbation reduction improvements and can serve as a steroid-sparing agent.
However, because there is no comparison of head-to-head No, it is not known whether a different mechanism of action they might be associated with different efficacy in a particular patient sub-phenotype. Long-term clinical observations will provide real-world evidence about their effectiveness and safety lasting.

interleukin -2-mediated 5 in the expression levels of CD8 + CD2 5 + regulatory T cells stat- relevance for asthma.
Preliminary studies suggest a potential role of cell CD8 + CD25 + regulatory T (Tregs) in asthma. However, the published data with respect to the relevance of signaling pathways that regulate homeostasis Tregs limited and contradictory. The first objective of this study was to characterize the phosphorylation of STAT-5 on CD8 + CD25 + Treg. The second objective is to investigate the ability of CD8 + CD25 + Treg from the patients and controls in response to interleukin (IL) -2 treatment in vitro.
Twenty-five healthy subjects (NC) and 50 patients with either severe (SA) or (MA) mild-moderate asthma were enrolled in this study. STAT-5 phosphorylation was detected in purified CD8 + CD25 + Treg from healthy and asthmatic subjects, suggesting that STAT-5 has a role in the pathobiology of them. At the beginning, asthmas have either significantly lower [(SA = 4.5 ± 5% vs. NC = 26 ± 25%, P <0.001) and (MA = 10 ± 7.5% vs NC = 26 ± 25%, P <0.001)] or higher [(SA = 54 ± 58.5% vs 26 ± 25%, P <0.01) and (MA = 71 ± 74.5% vs 26 ± 25%, P <0, 01) the proportion of Tregs express pstat-5 from the control. In contrast to healthy subjects, CD8 + CD25 + Treg from asthma have increased both subjects (pstat-5high) or decreased (pstat-5low) phosphorylated STAT-5 level in individual cells.
These data suggest that changes in the level of phosphorylation of Stat-5 may be associated with asthma and is a potential molecular basis of differentiation skewed CD8 + CD25 + Treg. IL-2 treatment of the cells of subjects, severe asthma increases the proportion of cells expressing high levels pstat-5 while the decline in the proportion of those expressing low levels of pstat-5. Strikingly, IL-2 increases the proportion of the second subset of subjects mild-moderate asthma.
