High expression of CD47 on several types of cancer cells has been identified as a ‘don't eat me signal' that inhibits their killing by macrophages or NK cells. CD47 is an antiphagocytic molecule that contributes to tumor cell resistance in host immune surveillance. CD47 overexpression correlated with tumor progression and shorter survival in lung cancer. However, the expression and functional significance of CD47 in Non‐Small Cell Lung Cancer (NSCLC) has not been completely understood.

The cancer tissue page shows antibody staining of the protein in 20 different cancers. CD47 is not prognostic in cervical cancer Alive (n=220) Dead (n=71) Female (n=291) Male (n=0) Stage: n/a (n=291) Moreover, SIRPα mutants ‘CV1’ and CD47 mutants ‘Velcro-CD47’ with high affinities have been reported to be adjuvants to augment the efficacy of therapeutic antibodies.9 10 For example, anti-human CD47 antibody (B6H12) can markedly suppress tumor growth in ovarian, breast, colon cancer, glioblastoma and acute lymphoblastic leukemia in NOD-scid Il2rγ null mice xenotransplantation Se hela listan på frontiersin.org 2019-03-05 · In 2009, researchers in the laboratory Stanford stem cell biologist Irving Weissman, MD, showed that CD47 on human leukemia stem cells acts as a "don't eat me" signal to the immune cells called macrophages that patrol the body to eliminate infected and diseased cells. Next-generation CD47 blockade has resulted in bispecific antibody platforms that can also target CD19 or CD20 in a mouse lymphoma model [80-82], CD33 or CD123 in AML [83-85], CD40 in colon carcinoma , tumor-associated antigens such as mesothelin and VEGFR1 in non-small cell lung cancer, and even dual blockade of CD47 and SIRPα [88,89] or SIRPα and PD-L1 ; however, trials in humans have yet Previous studies identified CD47 as a surface marker of human solid tumors including bladder cancer (13).

Cancer cells leverage CD47, a cell surface protein, as a “don’t eat me” signal to evade detection by the immune system.
When cancerous tumors form on connective tissues, it is a sarcoma. Sarcomas can either be bone or soft tissue, with additional sub-classifications depending on the origin of the cells (according to The Sarcoma Alliance). Sarcoma is rare and

Glioblastoma is an aggressive cancer of the brain. It is a very fast-growing cancer that spreads quickly. Glioblastoma is the most common type of malignant brain tumor in adults. When cancerous tumors form on connective tissues, it is a sarcoma. Sarcomas can either be bone or soft tissue, with additional sub-classifications depending on the origin of the cells (according to The Sarcoma Alliance). Sarcoma is rare and Whether colon cancer runs in your family or you’re interested in learning about health conditions as part of an effort to improve your well-being, it’s important to understand this type of cancer.

Integrin-associated protein (CD47) is ubiquitously expressed on the surface of cells and functions as an identifier of self. In blood cancer, tumor cells expressing CD47 evade phagocytosis by macrophages, leading to a poor patient prognosis. CD47 is an antiphagocytic molecule that acts via ligation to signal regulatory protein alpha on phagocytes; its enhanced expression and therapeutic targeting have recently been reported for several malignancies.
