Macrophage-derived MMP14 fosters immunosuppressive tumor microenvironment by regulating soluble semaphorin 4D

Abstract High expression of semaphorin 4D (SEMA4D) in tumor cells fosters an immunosuppressive tumor microenvironment (TME), yet the underlying tumor-macrophage crosstalk remains poorly understood. Here, we investigated this regulatory axis using in vitro co-cultures and SEMA4D g...

Preliminary analysis for the joint autonomous orbit determination of the BDS-3 MEO satellites and lunar ELFO satellites based on inter-satellite links

Abstract A fundamental limitation of Autonomous Orbit Determination (AOD) for Global Navigation Satellite Systems (GNSS) constellations using Inter-Satellite Links (ISLs) is the inherent unobservability of the overall rotational bias, leading to continuous degradation of orbit de...
