    In the human body, there is a type of white blood cells called macrophages, which can distinguish between "foe and self" and eliminate pathogens and abnormal cells without harming normal cells


    However, studies have found that tumor cells can use the CD47-SIRPα signaling pathway to escape the attack of the natural immune system


    AL008 is a new type of anti-SIRPα antibody developed by Alector


    In preclinical humanized mouse tumor models, AL008 single agent has shown the properties of inhibiting tumor growth and enhancing the activity of M1 macrophages


    In addition, AL008 can also promote the function of T cells


    It is hoped that the follow-up clinical research of the drug will proceed smoothly and achieve good results, which will bring new treatment options to patients as soon as possible
