Q: Background. Hepatitis C virus (HCV) is an underappreciated cause of pediatric liver disease, most frequently acquired by vertical transmission (VT). Current guidelines that include the option of screening infants for HCV RNA at 1-2 months are based on data prior to current real-time polymerase chain reaction (PCR)-based testing. Previous studies have demonstrated VT rates of 4%-15% and an association with high maternal viral load. We evaluated HCV RNA in infants with HCV VT and assessed maternal risk factors in a prospective cohort in Cairo, Egypt. Methods. Pregnant women were screened for HCV from December 2012 to March 2014. For those with HCV viremia, their infants were tested at 12 months for HCV RNA using real-time PCR. Maternal risk factors assessed for HCV VT association included HCV RNA levels, mode of delivery, and maternal IL28B genotype. Results. Of 2514 women screened, a total of 54 women were viremic (2.1%) and delivered 56 infants. Of those, 51 infants of 49 women were tested at 12 months of age. Only 7 infants were viremic, with an HCV VT rate of 14.3% (7 of 49). Median HCV RNA in the infants was 2100 IU/mL. None of the maternal risk factors analyzed were associated with transmission. Conclusions. In Egypt where HCV is highly endemic, we observed an overall 12-month HCV VT rate of 14.3%. Further studies should focus on better identification of pregnant women more likely to vertically transmit HCV and earlier testing of infants to identify those likely to develop chronicity.

Q: Macropinocytosis is a regulated form of endocytosis that mediates the non-selective uptake of solute molecules, nutrients and antigens. It is an actin-dependent process initiated from surface membrane ruffles that give rise to large endocytic vacuoles called macropinosomes. Macropinocytosis is important in a range of physiological processes; it is highly active in macrophages and dendritic cells where it is a major pathway for the capture of antigens, it is relevant to cell migration and tumour metastasis and it represents a portal of cell entry exploited by a range of pathogens. The molecular basis for the formation and maturation of macropinosomes has only recently begun to be defined. Here, we review the general characteristics of macropinocytosis, describe some of the regulators of this pathway, which have been identified to date and highlight strategies to explore the relevance of this endocytosis pathway in vivo.

Q: The T cell antigen-specific repertoire is thought to be shaped by thymic expression of self molecules. Since a myelin basic protein (MBP)-like gene (golli-MBP) has been reported to be expressed by cells of the immune system, the present study was undertaken to determine whether the golli-MBP gene was expressed in the mouse thymus and, if so, to characterize transcripts of this gene in this organ. Using exon-specific primers for MBP and golli-MBP, cDNA from thymus and other tissues was amplified, and the amplified products analyzed by Southern blotting with exon-specific oligonucleotide probes. The amplified products were subcloned, and the inserts characterized by DNA sequencing. The thymic transcripts were found to contain golli-MBP exons 1, 2, 3, 5A, 5B, 5C, 6, 7, 8, and 11.
