Pathways such as macropinocytosis which is the canonical pathway for EBOV entry. Our data indicate that MBL also mediates internalization of virus via macropinocytosis but suggests that MBL-mediated uptake preferentially utilizes microtubules compared with the canonical EBOV pathway which is dependent on both microtubules and actin. doi:10.1371/journal.pone.0060838.gcirculating C4 [88], we specula

We preincubated HIV-EBOZ GP virion-like particles (12,000 pg/ml) with PNGase F or endo H (10,000 U/ml each) diluted in DMEM or with DMEM alone for 1 hour at 37uC. Viruses then underwent gel electrophoresis;

Infections using high level rhMBL (10 mg/ml) in 5 serum (i.e. diluted 20-fold). However, such a high concentration of rhMBL is considered supraphysiological if adjusted for the 20-fold dilution factor of serum. Although human MBL is produced primarily in the liver, extrahepatic MBL synthesis has been found in the gastrointestinal tract, middle ear fluid, and nasopharyngeal secretions. It is possi

Ributed to the expansion in access to services for preventing mother-to-child transmission of HIV, the primary route of HIV acquisition in children. Sub-Saharan Africa is disproportionately represented in the epidemic with 69 of the global total of people living with HIV (UNAIDS 2012). An estimated 90 of the world's children living with HIV live in sub-Saharan Africa. At the end of 2011, 54 of
