Common asthma drug helps fight hard-to-treat cancers, including aggressive breast cancers, early study finds
An early study suggests that a common asthma drug may help treat hard-to-manage cancers, including aggressive breast cancers. The research indicates that blocking a specific protein could enhance the effectiveness of cancer immunotherapy. If confirmed, this finding could provide new options for patients resistant to current treatments.
- ▪The study focuses on the protein cysteinyl leukotriene receptor 1 (CysLTR1), which tumors may exploit to weaken immune responses.
- ▪Montelukast, an existing asthma medication, can block CysLTR1 and potentially reprogram immune cells to fight cancer more effectively.
- ▪The research highlights the role of neutrophils in cancer resistance to immunotherapy, suggesting a new therapeutic approach.
