Project description:To test the role of FAO in epithelium differentiation, we assessed genome-wide transcriptional changes in Cpt1a+/- and Cpt1a-/- primary mouse tracheal epithelial cell (mTEC) cultures analysed at the end of the expansion phase (ALI day 0) or at day 5 and 7 post air-exposure by RNA-seq.

Project description:Influenza viruses pose a significant burden on global human health. Influenza has a broad cellular tropism in the airway, but how infection of different epithelial cell types impacts replication kinetics and burden in the airways is not fully understood. Using primary human airway cultures, which recapitulate the diverse epithelial cell landscape of the human airways, we investigated the impact of cell type composition on virus tropism and replication kinetics. Cultures were highly diverse across multiple donors and 30 independent differentiation conditions and supported a range of influenza replication. Although many cell types were susceptible to influenza, ciliated and secretory cells were predominantly infected. Despite the strong tropism preference for secretory and ciliated cells, which consistently make up 75% or more of infected cells, only ciliated cells were associated with increased virus production. Surprisingly, infected secretory cells were associated with overall reduced virus output. These data highlight the heterogeneous outcomes of influenza virus infections in primary human airway cultures and the disparate impacts of infected cell identity on burst size, even among preferentially infected cell types.

Abstract:
Seasonal and pandemic influenza A virus (IAV) continues to
be a public health threat. However, we lack a detailed and
quantitative understanding of the immune response kinetics to
IAV infection and which biological parameters most strongly
influence infection outcomes. To address these issues, we use
modeling approaches combined with experimental data to
quantitatively investigate the innate and adaptive immune
responses to primary IAV infection. Mathematical models were
developed to describe the dynamic interactions between target
(epithelial) cells, influenza virus, cytotoxic T lymphocytes
(CTLs), and virus-specific IgG and IgM. IAV and immune kinetic
parameters were estimated by fitting models to a large data set
obtained from primary H3N2 IAV infection of 340 mice. Prior to
a detectable virus-specific immune response (before day 5), the
estimated half-life of infected epithelial cells is
approximately 1.2 days, and the half-life of free infectious
IAV is approximately 4 h. During the adaptive immune response
(after day 5), the average half-life of infected epithelial
cells is approximately 0.5 days, and the average half-life of
free infectious virus is approximately 1.8 min. During the
adaptive phase, model fitting confirms that CD8(+) CTLs are
crucial for limiting infected cells, while virus-specific IgM
regulates free IAV levels. This may imply that CD4 T cells and
class-switched IgG antibodies are more relevant for generating
IAV-specific memory and preventing future infection via a more
rapid secondary immune response. Also, simulation studies were
performed to understand the relative contributions of
biological parameters to IAV clearance. This study provides a
basis to better understand and predict influenza virus
immunity.

Project description:Oligonucleotide microarrays were used to establish a profile for gene expression in wild-type airway epithelial cells after paramyxoviral infection. Analysis was performed on mRNA isolated from SeV-infected primary-culture mouse tracheal epithelial cells that were maintained under physiologic conditions (air-liquid interface). Experiment Overall Design: Primary-culture mouse tracheal epithelial cells (mTECs) were established on Transwell membranes using air-liquid interface (ALI) conditions. Sendai virus (SeV), strain 52, was obtained from American Type Culture Collection and stored at -70°C. Cultures were inoculated with SeV or an equivalent amount of UV-inactivated SeV (SeV-UV) in the apical compartment for 1 h at 37 °C. Air-liquid-interface conditions were re-established by washing the membrane with PBS. Each culture well was subjected to one of two treatments (SeV, or UV-SeV) for 1 day. N = 4 SeV wells, N = 6 UV-SeV wells, with each well independently analyzed by microarray. No technical replicates were performed, but arrays were evaluated for quality control using the SimpleAffy package (Miller CJ, 2004) in Bioconductor 2.0.

Project description:To investigate how murine airway epithelial cells respond to Influenza infection and how important interferon type I signaling is for this response, we harvested airway epithelial cells from the tracheas of wild type, interferon type I knockout(IFNaR-/-) and STAT1 knockout (STAT1-/-) mice and cultured them as previously described (Pickles et al,1998) in polarized airway epithelial cell cultures (mAECs). Triplicate mAECs from each type of mouse (wt,IFNaR-/-,STAT1-/-) were infected with 2X105 PFUs Influenza A (WSN) for 2h or mock inoculated and harvested 24h after infection. Triplicate murine polarized airway epithelial cell cultures from wild type, IFNaR-/- or STAT1-/- mice were mock treated or infected with 2x10^5 PFUs of Influenza A (WSN) for 2h and harvested 24 h post infection.
