Paragraph: Primary human airway epithelial cell (hAEC) cultures represent a universal platform to propagate respiratory viruses and characterize their host interactions in authentic target cells. To further elucidate specific interactions between human respiratory viruses and important host factors in the airway epithelium, it is important to make hAEC cultures amenable to genetic modification. However, the short and finite lifespan of primary cells in cell culture creates a bottleneck for the genetic modification of these cultures. In the current study, we show that the incorporation of the Rho-associated protein kinase (ROCK) inhibitor (Y-27632) during cell propagation extends the life span of primary human cells in vitro and thereby facilitates the incorporation of lentivirus-based expression systems. Using fluorescent reporters for fluorescence-activated cell sorting (FACS)-based sorting, we generated homogenously fluorescent hAEC cultures that differentiate normally after lentiviral transduction. As a proof-of-principle, we demonstrate that host gene expression can be modulated post-differentiation via inducible short hairpin (sh)RNA-mediated knockdown. Importantly, functional characterization of these transgenic hAEC cultures with exogenous poly (I:C), as a proxy for virus infection, demonstrates that such modifications do not influence the host innate immune response. Moreover, the propagation kinetics of both human coronavirus 229E (HCoV-229E) and human respiratory syncytial virus (hRSV) were not affected. Combined, these results validate our newly established protocol for the genetic modification of hAEC cultures, thereby unlocking a unique potential for detailed molecular characterization of virus-host interactions in human respiratory epithelium.

Paragraph: Children are more vulnerable to the risks of air pollution, including susceptibility to acquiring chronic diseases in their developing lungs. Despite these, there are no specific masks designed for and tested in children that are available to protect our young from the common particulate air pollutants today. We evaluated safety, fit and comfort of a specially designed paediatric N95 mask with an optional micro ventilator (micro fan, MF) in healthy children aged 7-14 years, in a randomized, two-period crossover design. The subjects' cardiorespiratory physiological measurements were assessed in different states of physical activity under different interventions (mask without and with MF). A total of 106 subjects were recruited between July-August 2016. The use of the mask without MF increased the End-Tidal CO 2 (etco 2 ) and fractional concentration of inspired co 2 (fico 2 ) at rest and on mild exertion, as expected. The use of the mask with MF brought FICO 2 levels comparably closer to baseline levels without the mask for both activities. The mask, with or without the MF, was found to be well fitting, comfortable and safe for use in children at rest and on mild exertion. The N95 mask tested offers a promising start for more studies in the paediatric population. Air pollution, such as haze or smog, is an evolving and increasingly significant problem around the world. A wide range of hazards of chronic air pollution in children include nocturnal cough, asthma, poor performance in neurobehavioral function, negative impact in cognitive development and harmful effects on brain development 1-5 . In particular, children represent a vulnerable segment of any population. They carry more risks of long term exposure to pollution over the course of their lives and are susceptible to acquiring chronic diseases in their developing lungs 6-11 . Use of masks and respirators can offer protection against air pollutants. However, the commercially available disposable particulate respirators, typically certified for surgical (which may only offer some barrier against larger particles) and occupational use, are mainly designed for and studied in adults. The test standards are specified according to adult breathing conditions and fit. There are to date, no masks designed for and evaluated in children. Several studies have investigated the effectiveness, safety, fit and comfort of different types of masks 12-15 . However these studies were done only in adult populations. Even alternatives such as cloth masks have been tested only in adult populations 16 . In another study, the facemasks for paediatric use (FPU, the masks that are not specifically designed for paediatric use but are the existing mask that may be used for children during emergency situation like that of airborne disease outbreaks) were tested mainly to evaluate the leakage associated with donning the FPU 17 . This study did show superiority of FPU in comparison to surgical masks in certain aspects, however, the study was not performed in children. One study was performed in children to evaluate the redesigned open system face mask. However, the objective of this study was to evaluate the mask for monitoring P ETCO2 during sedation in clinical practice and the children in this study donned the mask only for 30 sec. 18 . These and other similar studies merely point to the fact that there are no masks that are specifically designed and tested in children such that they can be prescribed for paediatric use in the setting of daily routine activities. In our study, the N95 masks were specifically designed for use in children and they were evaluated in children under conditions of routine daily activities. They are the first to be paired with a micro ventilator (micro fan, MF), designed to reduce the accumulation of exhaled carbon dioxide (CO 2 ), heat and humidity in the dead space of

Paragraph: Porcine epidemic diarrhea virus (PEDV) is an emerging pathogenic coronavirus that causes a significant economic burden to the swine industry. The virus infects the intestinal epithelium and causes villous atrophy, resulting in diarrhea and dehydration. Interaction of the viral spike (S) surface glycoprotein through its S1 subunit with the host cell receptor is the first step in infection and the main determinant for virus tropism. As for several other alphacoronaviruses including the porcine transmissible gastroenteritis virus (TGEV) and the human coronavirus 229E (HCoV-229E), the aminopeptidase N (APN) protein was reported to be a functional receptor for PEDV. In this study we examined the role of APN as a receptor. We show that overexpression of porcine APN renders MDCK cells susceptible to TGEV, but not to PEDV. Consistently, unlike TGEV-S1, PEDV-S1 exhibited no binding to cell-surface expressed APN or to a soluble version of APN. Moreover, preincubation of these viruses with soluble APN or pretreatment of APN expressing ST cells with soluble TGEV-S1 blocked TGEV infection, but had no effect on infection by PEDV. The combined observations indicated that APN is not required for PEDV infection. To definitively prove this conclusion, we applied CRISPR/Cas9 genome engineering to knock out APN expression in PEDV-susceptible porcine (ST) and human cell lines (Huh7 and HeLa). As a consequence these cells no longer bound TGEV-S1 and HCoV-229E-S1 at their surface and were resistant to infection by the corresponding viruses. However, genetic ablation of APN expression had no effect on their infectability by PEDV, demonstrating that APN is not essential for PEDV cell entry.
