Anti-Human IL5 Recombinant Antibody (TAB-031)

CAT#: TAB-031

Recombinant monoclonal antibody to Human IL5. It is a humanized monoclonal antibody that recognizes interleukin-5 (IL-5), and is used to treat certain kinds of asthma and white blood cell diseases. Recent studies have concluded that mepolizumab may improve exacerbations in patients with severe eosinophilic asthma, an adult-onset asthma which represents less than 5% of all asthma. IL-5 is a chemical messenger in the immune system that stimulates the growth of eosinophils. In eosinophilic asthma, eosinophils are present in the lungs. When mepolizumab was given to people with eosinophilic asthma, it eliminated eosinophils from the bloodstream,and reduced eosinophils in the lungs and bone marrow.

    This study investigates the effectiveness of targeting the IL-5 pathway in addressing airway hyperresponsiveness (AHR) in asthma by comparing two monoclonal antibodies, benralizumab and mepolizumab. The research focuses on their ability to modulate AHR in human airways passively sensitized to mimic asthmatic conditions. The study measures the inhibition of AHR to histamine, parasympathetic activation, and mechanical stress, as well as the modulation of cyclic AMP (cAMP) levels. The results demonstrate that both benralizumab and mepolizumab significantly reduce AHR, with benralizumab being more potent. The study concludes that targeting the IL-5/IL-5Rα axis is an effective strategy for preventing AHR.
    Creative Biolabs provided the benralizumab (Cat# TAB-222) and mepolizumab (Cat# TAB-031) used in this study. These antibodies were essential for the comparative analysis of their effects on AHR and cAMP levels in human bronchial tissues. The use of these reagents allowed the researchers to determine the differential potency and efficacy of benralizumab and mepolizumab in modulating AHR, thus contributing significantly to the understanding of their therapeutic potential in treating asthma.
