The CD47 knockout mice absorbed hematomas more significantly than those in the normal group and with less lesions in the brain tissues.123 In TLR4 gene knockout mice with ICH, they found increased expression of microglia and CD36 due to the characteristic of CD36 to induce a strong erythrocyte phagocytosis and therefore accelerate hematoma absorption.124. The gene discussed is CD36; the disease is hematoma.
