Abstract
Glycans are present in all living organisms, including viruses, bacteria, and animals, and perform various biological functions. The author has been studying influenza viruses' glycan usage mechanisms, particularly the functional analysis of neuraminidase (NA), a viral sialidase. The authors recently focused on influenza virus NAs' high sialidase activity with the aim of using sialidase activity detection as a virus detection technology. Using the probe BTP3-Neu5Ac, allows fluorescent imaging of sialidase activity, we created a new technique for easy, rapid, and high sensitivity fluorescent imaging of virus-infected cells. The detection of viruses using BTP3-Neu5Ac does not require specific antibodies and can be performed by simply adding reagents. Furthermore, fluorescence imaging of sialidase as a virus detection technology has many advantages, including isolating viruses from fluorescently imaged infected cells. This detection technique is easy to use in basic research and hygiene testing, where viral culture is conducted and is expected to be widely used.

Abstract
Immunostaining with an antiviral antibody is usually performed to visualize virus-infected cells. In contrast, this study established an easy method for fluorescence (FL) imaging of cells infected with influenza A and B viruses and some paramyxoviruses without the need for cell fixation and an antiviral antibody. These viruses and the cells they have infected express the viral surface enzymes "neuraminidase" or "hemagglutinin-neuraminidase," which show sialidase activity. Sialidase activity is fluorescently visualized by using a sialidase fluorogenic probe developed in our previous study. The probe enables histochemical FL imaging of the virus-infected cells and applies to virus isolation and detection of an influenza virus resistant to sialidase inhibitors anti-influenza drugs.

The Function of Sialidase Revealed by Sialidase Activity Imaging Probe. Int J Mol Sci 2021; 22:ijms22063187.

Abstract
Sialidase cleaves sialic acid residues from glycans such as glycoproteins and glycolipids. In the brain, desorption of the sialic acid by sialidase is essential for synaptic plasticity, learning and memory and synaptic transmission. BTP3-Neu5Ac has been developed for sensitive imaging of sialidase enzyme activity in mammalian tissues. Sialidase activity in the rat hippocampus detected with BTP3-Neu5Ac increases rapidly by neuronal depolarization. It is presumed that an increased sialidase activity in conjunction with neural excitation is involved in the formation of the neural circuit for memory. Since sialidase inhibits the exocytosis of the excitatory neurotransmitter glutamate, the increased sialidase activity by neural excitation might play a role in the negative feedback mechanism against the glutamate release. Mammalian tissues other than the brain have also been stained with BTP3-Neu5Ac. On the basis of information on the sialidase activity imaging in the pancreas, it was found that sialidase inhibitor can be used as an anti-diabetic drug that can avoid hypoglycemia, a serious side effect of insulin secretagogues. In this review, we discuss the role of sialidase in the brain as well as in the pancreas and skin, as revealed by using a sialidase activity imaging probe. We also present the detection of influenza virus with BTP3-Neu5Ac and modification of BTP3-Neu5Ac.

Abstract
Sialidases are widely distributed in nature and are involved in many physiological and pathological processes. Sialidases are expressed and work in various tissues and organelles. Clarification of the localization of sialidases is very helpful as a way to understand their functions. We previously developed a novel fluorogenic probe for sialidases, BTP3-Neu5Ac, that visualized the localization of sialidase activity in live cells and tissues by precipitating the hydrophobic fluorescent compound; however, for the purpose of accurate fluorescence imaging of sialidase-expressing cells or the distribution of intracellular sialidase activity, BTP3-Neu5Ac was inadequate in imaging performance. We report the design and development of a sialidase imaging probe that improves the sensitivity and accuracy of in situ fluorescence imaging performance as well as increases the hydrophobicity by attaching linear unsaturated hydrocarbon chains into the hydrophobic fluorescent compound of BTP3-Neu5Ac. The newly developed probe showed low diffusivity and high brightness for fluorescence imaging, and it enabled sensitive and highly accurate imaging of viral sialidase in virus-infected cells and sialidase-expressing cells as well as mammalian sialidase in the rat brain. The probe also enabled the fluorescence imaging of intracellular viral sialidase in live-virus-infected cells. The newly developed probe is expected to be a useful tool that will contribute to the progress of research on sialidases in various fields such as research on viruses and brains.

Abstract
Reagents to visualize and localize neuraminidase activity would be valuable probes to study the role of neuraminidases in normal cellular processes as well as during viral infections or cancer development. Herein, a new class of neuraminidase-imaging probes that function as proximity ligation reagents by releasing a highly reactive fluorophore that tags nearby cellular material is described. It is further demonstrated that it is possible to create an influenza virus-specific reagent, which can specifically detect influenza virus infections in mammalian cells. These reagents have potential use as specific histological probes independent of viral antigenicity and, therefore, offer some advantages over commonly used anti-neuraminidase antibodies.

Abstract
Sialidase releases sialic acid residues from the ends of sugar chains. The sialidases are involved in many physiological processes including cell differentiation and proliferation and immune function as well as pathophysiological conditions such as various human cancers and infections. Therefore visualization of sialidase activities with high sensitivity could provide valuable insights into these isozyme's activity. We developed novel fluorescent sialidase substrates, 2-benzothiazol-2-yl-phenol derivatives-based N-acetylneuraminic acid (Neu5Ac) (BTP-Neu5Ac) substrates, for highly sensitive and specific visualization of sialidase activity in living mammalian tissues and virus-infected cells. We found that BTP-Neu5Ac can visualize sialidase activities sensitively and selectively in rat tissues including brain slices. BTP-Neu5Ac can also clearly detect cancer cells implanted orthotopically in mouse colons and human colon cancers. In this review, I describe imaging of sialidase activity with BTP-Neu5Ac in animal tissues, detection of colon cancer, memory formation, detection of virus-infected cells, and application to drug-resistant influenza virus detection and separation.

Abstract
Immunochromatographic kits and RT-PCR are widely used as diagnostic tools for influenza detection in clinical and hygiene fields. Immunochromatographic kits are useful for differential typing of influenza A and influenza B but cannot show if the detected virus strains have acquired drug resistance against neuraminidase inhibitors that target sialidase activity of viral neuraminidase. Although RT-PCR enables determination of drug-resistant mutants, its efficacy is limited to viruses carrying a known substitution in their neuraminidase genome sequence. In the present study, an easy, rapid and sensitive method for detection of drug-resistant influenza viruses regardless of major antigenic changes or genomic mutations was developed. By using the method in combination with virus-concentrated membranes in centrifugal filter units and a sialidase imaging probe, 2-(benzothiazol-2-yl)-4-bromophenyl-N-acetylneuraminic acid (BTP3-Neu5Ac), sialidase activity of influenza neuraminidase was visualized on membranes by the green fluorescence of produced hydrophobic BTP3 under UV irradiation with a handheld UV flashlight. Fluorescence images in the presence or absence of neuraminidase inhibitors clearly discriminated drug-resistant influenza viruses from drug-sensitive ones. The assay can be done within 15 min. The detection sensitivity was shown to be equal to or higher than the sensitivities of commercial immunochromatographic kits. The assay will be a powerful tool for screening and monitoring of emerging drug-resistant influenza viruses and would help clinicians decide effective antiviral treatment strategies when such mutants have become prevalent.

Abstract
Sialidase removes sialic acid residues from sialoglycoconjugates such as glycoproteins and glycolipids. Since sialic acid plays crucial roles in synaptic plasticity and memory in the hippocampus, the regulation of sialyl signaling by sialidase is also necessary for neural functions. However, since mammalian sialidase activity is remarkably weak, it has been difficult to detect sialidase activity in mammalian tissues. Determination of the distribution of sialidase activity in living mammalian tissues would provide much valuable information for understanding the roles of sialidase in physiological functions. Therefore, we synthesized a novel benzothiazolylphenol-based sialic acid derivative (BTP-Neu5Ac) as a fluorescent sialidase substrate. After cleavage of BTP-Neu5Ac, which is water soluble and shows little fluorescence, with sialidase, the water-insoluble fluorophore benzothiazolylphenol (BTP) released from BTP-Neu5Ac stains tissue and shows bright fluorescence. BTP-Neu5Ac can visualize sialidase activity in brain tissue with high levels of sensitivity and specificity. The sialidase expression level is markedly high in various human cancers such as colon, renal, prostate, and ovarian cancers. BTP-Neu5Ac can detect human colon cancers sensitively. Thus, BTP-Neu5Ac is useful not only for physiological research but also as a cancer probe. BTP-Neu5Ac is now being used in virology research. In this review, methods for histochemical imaging of sialidase activity and the role of sialidase in hippocampal memory are described based on the author's study of multidimensional analysis of hippocampal excitatory neurotransmission and development of analytical tools for glycans, which was awarded a prize by the Tokai branch of the Pharmaceutical Society of Japan.

Abstract
Influenza A and B viruses possess a neuraminidase protein that shows sialidase activity. Influenza virus-specific neuraminidase inhibitors (NAIs) are commonly used for clinical treatment of influenza. However, some influenza A and B viruses that are resistant to NAIs have emerged in nature. NAI-resistant viruses have been monitored in public hygiene surveys and the mechanism underlying the resistance has been studied. Here, we describe a new assay for selective detection and isolation of an NAI-resistant virus in a speedy and easy manner by live fluorescence imaging of viral sialidase activity, which we previously developed, in order to achieve high-efficiency capture of an NAI-resistant virus. An NAI-resistant virus maintains sialidase activity even at a concentration of NAI that leads to complete deactivation of the virus. Infected cells and focuses (infected cell populations) of an oseltamivir-resistant virus were selectively visualized by live fluorescence sialidase imaging in the presence of oseltamivir, resulting in high-efficiency isolation of the resistant viruses. The use of a combination of other NAIs (zanamivir, peramivir, and laninamivir) in the imaging showed that the oseltamivir-resistant virus isolated in 2008 was sensitive to zanamivir and laninamivir but resistant to peramivir. Fluorescence imaging in the presence of zanamivir also succeeded in selective live-cell visualization of cells that expressed zanamivir-resistant NA. Fluorescence imaging of NAI-resistant sialidase activity will be a powerful method for study of the NAI resistance mechanism, for public monitoring of NAI-resistant viruses, and for development of a new NAI that shows an effect on various NAI-resistant mutations.

Abstract
Human parainfluenza virus type 1 (hPIV1) does not form clear plaque by the conventional plaque formation assay because of slightly a cytopathic effects in many cell lines infected with hPIV1, thus making in virus titration, isolation and inhibitor evaluation difficult. We have succeeded in fluorescent histochemical visualization of sialidase activities of influenza A and B viruses, Newcastle disease virus and Sendai virus by using a novel fluorescent sialidase substrate, 2-(benzothiazol-2-yl)-4-bromophenyl 5-acetamido-3,5-dideoxy-α-D-glycero-D-galacto-2-nonulopyranosidonic acid (BTP3-Neu5Ac). In this study, we applied the BTP3-Neu5Ac assay for rapid detection of hPIV1 and hPIV type 3. The BTP3-Neu5Ac assay could histochemically visualize dot-blotted hPIVs on a membrane and hPIV-infected cells as local fluorescence under UV irradiation. We succeeded in distinct fluorescent visualization of hPIV1-infected cells in only 3 d using the BTP3-Neu5Ac assay. Due to there being no fixation, hPIV1 was isolated directly from fluorescent stained focus cells by the BTP3-Neu5Ac assay. Establishment of a sensitive, easy, and rapid fluorescent focus detection assay for hPIV, hPIV1 in particular will contribute greatly to progress in hPIV studies.

Abstract
Mumps viruses show diverse cytopathic effects (CPEs) of infected cells and viral plaque formation (no CPE or no plaque formation in some cases) depending on the viral strain, highlighting the difficulty in mumps laboratory studies. In our previous study, a new sialidase substrate, 2-(benzothiazol-2-yl)-4-bromophenyl 5-acetamido-3,5-dideoxy-α-D-glycero-D-galacto-2-nonulopyranosidonic acid (BTP3-Neu5Ac), was developed for visualization of sialidase activity. BTP3-Neu5Ac can easily and rapidly perform histochemical fluorescent visualization of influenza viruses and virus-infected cells without an antiviral antibody and cell fixation. In the present study, the potential utility of BTP3-Neu5Ac for rapid detection of mumps virus was demonstrated. BTP3-Neu5Ac could visualize dot-blotted mumps virus, virus-infected cells, and plaques (plaques should be called focuses due to staining of infected cells in this study), even if a CPE was not observed. Furthermore, virus cultivation was possible by direct pick-up from a fluorescent focus. In conventional methods, visible appearance of the CPE and focuses often requires more than 6 days after infection, but the new method with BTP3-Neu5Ac clearly visualized infected cells after 2 days and focuses after 4 days. The BTP3-Neu5Ac assay is a precise, easy, and rapid assay for confirmation and titration of mumps virus.
