生物活性

Cabiralizumab (FPA 008) is an anti-CSF1R monoclonal antibody (MAb). Cabiralizumab enhances T cell infiltration and antitumor T cell immune responses. Cabiralizumab inhibits the activation of osteoclasts and blocks bone destruction, and can be used in the research of rheumatoid arthritis (RA). Cabiralizumab can combine with Nivolumab (HY-P9903) for lung cancer research[1][2][3][4].

体外研究
(In Vitro)

Cabiralizumab (7 天) 在体外培养的胰腺导管腺癌 (PDAC) 的门静脉血单核细胞 (PortalBMC) 未分类样本中可破坏循环肿瘤细胞 (CTC) 簇形成,并增加 CTC 凋亡[4]
Cabiralizumab (7 天) 在体外培养的 PDAC 的 PortalBMC 中可重新激活 T 细胞 (CD3+CD25+CTLA4-PD1L1-) 并增加的 IFNγ 产生[4]

体内研究
(In Vivo)

Cabiralizumab (200-400 μg;腹腔注射;每周两次,共 5 次) (αCSF1R) 具有抗肿瘤活性,其在小鼠模型中高剂量效果不如低剂量3.

Animal Model: C57Bl6 male mice model (YUMMER1.7 (UV irradiated derivative of YUMM1.7 carrying a higher number of somatic mutations) or YUMM1.7 (BrafV600E /Pten−/−, Cdkn2a−/−) cells were subcutaneously injected into the left flank) (8-9 week old)[3]
Dosage: 200, 400 μg
Administration: Intraperitoneal injection (i.p.); twice a week for 5 times
Result: In the group treated with higher dose αCSF1R, 55% of mice (11/20) reached endpoint, whereas mice treated with lower dose αCSF1R fared better with 25% (5/20) reaching the endpoint in YUMMER1.7 mice model.
Lower αCSF1R dose resulted in improved survival compared to the higher αCSF1R dose in YUMMER1.7 mice model.
Treatment with both lower and higher anti-CSF1R dose delayed the tumor growth, but all tumors eventually grew out to endpoint in YUMM1.7 mice model.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
