Myeloid-resident neuropilin-1 promotes choroidal neovascularization while mitigating inflammation.

Age-related macular degeneration (AMD) in its various forms is a leading cause of blindness in industrialized countries. Here, we provide evidence that ligands for neuropilin-1 (NRP1), such as Semaphorin 3A and VEGF-A, are elevated in the vitreous of patients with AMD at times of active choroidal neovascularization (CNV). We further demonstrate that NRP1-expressing myeloid cells promote and maintain CNV.

Development of four-stage moving bed biofilm reactor train with a pre-denitrification configuration for the removal of thiocyanate and cyanate.

Two trains (A and B) of four-stage moving bed biofilm reactors (MBBRs) were developed for the degradation of thiocyanate (SCN(-)), cyanate (OCN(-)) and ammonia (NH3). A pre-denitrification configuration was established in the first-stage reactor of the B train using SCN(-) and OCN(-) as the sole carbon source. SCN(-), OCN(-) and NH3 were completely removed in both trains.

Simultaneous production of two foreign proteins from a polyvirus-based vector.

With the aim of developing a biotechnological tool for the production of foreign proteins in plants, we first engineered an infectious turnip mosaic virus (TuMV) cDNA that contained the jellyfish green fluorescent protein (GFP) gene or the bacterial beta-glucuronidase (GUS) gene (uidA). Two insertion sites were assessed, either between P1 and HCPro cistrons or Pol and CP cistrons. In each construct, the junctions flanking the inserted gene coded for P1 and/or VPg-Pro cleavage recognition site sequences, to produce free GUS or GFP.
