Abstract
Even after more than two years of intensive research, not all of the pathophysiological processes of Coronavirus Disease 2019 (COVID-19), induced by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection, have been fully elucidated. The initial virus-host interaction at the respiratory epithelium plays a crucial role in the course and progression of the infection, and is highly dependent on the glycosylation pattern of the host cell and of the secreted mucins. Glycans are polysaccharides that can be attached to proteins and thereby add to their stability and functionality. Lectins are glycan-binding proteins that recognize specific glycan motifs, and lectin histochemistry is a suitable tool to visualize and examine glycosylation pattern changes in tissues. In this study we used lectins with different glycan-specificities for the visualization of glycosylation pattern changes in the respiratory tract of SARS-CoV-2 infected Golden Syrian hamsters. While some lectins (LEL, STL) enable the visualization of the damage to alveolar type 1 pneumocytes, other lectins, e.g., GSLI, visualized the loss and subsequent hyperplasia of type 2 pneumocytes. UEAI staining was co-localized with KI67, a proliferation marker. Double staining of lectins LEL, STL and WGA with specific immune cell markers (Iba1, CD68) showed co-localization and the dominant infiltration of monocyte-derived macrophages into infected alveolar tissue. The elucidation of the glycosylation pattern of the respiratory tract cells in uninfected and infected Golden Syrian hamsters revealed physiological and pathological aspects of the disease that may open new possibilities for therapeutic development.

Abstract
BACKGROUND Airway epithelial cells provide a protective barrier against environmental particles including potential pathogens. Epithelial repair in response to tissue damage is abnormal in asthmatic airway epithelium in comparison to the repair of normal epithelium after damage. The complex mechanisms coordinating the regulation of the processes involved in wound repair requires the phased expression of networks of genes. Small non-coding RNA molecules termed microRNAs (miRNAs) play a critical role in such coordinated regulation of gene expression. We aimed to establish if the phased expression of specific miRNAs is correlated with the repair of mechanically induced damage to the epithelium. METHODS To investigate the possible involvement of miRNA in epithelial repair, we analyzed miRNA expression profiles during epithelial repair in a cell culture model using TaqMan-based quantitative real-time PCR in a TaqMan Low Density Array format. The expression of 754 miRNA genes at seven time points in a 48-hour period during the wound repair process was profiled using the bronchial epithelial cell line 16HBE14o- growing in monolayer. RESULTS The expression levels of numerous miRNAs were found to be altered during the wound repair process. These miRNA genes were clustered into 3 different patterns of expression that correlate with the further regulation of several biological pathways involved in wound repair. Moreover, it was observed that expression of some miRNA genes were significantly altered only at one time point, indicating their involvement in a specific stage of the epithelial wound repair. CONCLUSIONS In summary, miRNA expression is modulated during the normal repair processes in airway epithelium in vitro suggesting a potential role in regulation of wound repair.

Abstract
The α(1,6)-fucose attached to the core N-glycan (core fucose) of glycoproteins has been known to play essential roles in various pathophysiological events, including oncogenesis and metastasis. Aspergillus oryzae lectin (AOL) encoded by the fleA gene has been reported to bind to N-glycans containing core fucose. The fleA gene encoding AOL was cloned into an Escherichia coli expression vector and then fused with genes of fluorescent proteins for production of fusion proteins. The resulting FleA-fluorescent fusion proteins were expressed well in E. coli and shown to detect glycoproteins containing N-glycans with core fucose by lectin blot assay. It was also shown to bind to the surface of cancer cells highly expressing the fucosyltransferase VIII for attachment of core fucose. Surprisingly, we found that FleA-fluorescent fusion proteins could be internalized into the intracellular compartment, early endosome, when applied to live cells. This internalization was shown to occur through a clathrin-mediated pathway by endocytosis inhibitor assay. Taken together, these results suggest that FleA-fluorescent fusion proteins can be employed as a valuable fluorescent probe for the detection of fucosylated glycans and/or a useful vehicle for delivery of substances to the inside of cells.
