    BIOCELL, Vol.45, No.2, pp. 229-257, 2021, DOI:10.32604/biocell.2021.014338
    Abstract Integrin molecules are transmembrane αβ heterodimers involved in cell adhesion, trafficking, and signaling. Upon activation, integrins undergo dynamic conformational changes that regulate their affinity to ligands. The physiological functions and activation mechanisms of integrins have been heavily discussed in previous studies and reviews, but the fluorescence imaging techniques –which are powerful tools for biological studies– have not. Here we review the fluorescence labeling methods, imaging techniques, as well as Förster resonance energy transfer assays used to study integrin expression, localization, activation, and functions.

    (This article belongs to this Special Issue: Biomonitoring of Toxic Effects Using OMICs Markers)
    Abstract Carbon nanotubes (CNTs) have tremendous applications in almost every walk of life; however, their harmful impacts on humans and the environment are not well addressed. CNTs have been used in various applications ranging from medical science to different engineering branches, to ease human life. Generally, the toxicological profile of CNTs under laboratory conditions cannot be assessed primarily in medical science due to the inconsistent availability of cytotoxic study data. CNT toxicity has been affected by many physicochemical properties (e.g., size, type of functionalization), concentration, the extent of exposure, mode of exposure, and even the solvents/medium used to dissolve/disperse CNTs for… More >

    BIOCELL, Vol.45, No.2, pp. 331-337, 2021, DOI:10.32604/biocell.2021.010701
    Abstract Water buffalo (Bubalus bubalis) and domestic cattle (Bos taurus) are closely related species. However, embryo transfer interspecies has been attempted without any success. The failure in hybrid embryo-implantation is associated with the glycocode in the maternal-fetal interface. Glycosylation patterns have been studied in different species of ruminants; however, in B. bubalis, only the binucleated cells (BNC) have been analyzed. This glycocode is essential for a successful embryo-implantation and can be defined by Lectin-Histochemistry (LHC). The aim of this study is to compare the glycosylation pattern of placenta and uterus in water buffaloes and cattle by LHC. Tissue samples of placenta… More >

    BIOCELL, Vol.45, No.2, pp. 387-394, 2021, DOI:10.32604/biocell.2021.013824
    Abstract Hippophae rhamnoides L. is a plant of immense ethnopharmacological importance and is a known source for various valuable biochemicals and nutraceuticals. The production of folate, a vitamin involved in several vital functions, in this plant is rather poorly understood. Herein, we investigate the hypothesis that rhizobial bacteria serve the plant in this essential vitamin’s biosynthesis. Bacterial strains of Bacillus, Azorhizobium, Frankia, Paenibacillus, Brevibacillus and Pseudomonas, were isolated from the rhizosphere of the plant. HPLC and LCMS were used to trace the production of intra and extra-cellular folate by representative rhizospheric bacterial strains in vitro. From the seventeen functionally characterized bacterial… More >

    (This article belongs to this Special Issue: New Insights in Biology of Depression: New Molecules and Approaches)
    Abstract Mast cells are the main effector cells in IgE-associated allergic disorders, and we have reported that mucosal mast cells (MMCs) play a more important role in the development of food allergy (FA). IgE with antigen or calcium ionophore stimulation can lead to the activation of MMCs via a calcium-dependent pathway. The purpose of the present study was to identify gene signatures with IgE/antigen (dinitrophenyl-bovine serum albumin, DNP-BSA) or calcium ionophore (A23187) on the activation of MMCs. Differentially expressed genes between the two types of samples were identified with microarray analysis. Gene ontology functional and pathway enrichment analyses of differentially expressed… More >

    Abstract Schizophrenia is a common and serious mental illness characterized by severe impairments in thinking, emotions, and behaviors. Usually, the cognitive deficits of schizophrenia are closely associated with abnormal neurogenesis due to the hypofunction of certain neural receptors such as N-methyl-D-aspartate receptors (NMDARs), which mediates neurotransmission. However, little is known about the involvement of NMDAR1 in regulating hippocampal neurogenesis in schizophrenia. In the current study, we present evidence suggesting that NMDAR1 regulates hippocampal neurogenesis as lentivirus-mediated shRNA silencing NMDAR1 gene or blocking with MK-801 results in abnormal neurogenesis consistently found in schizophrenia. The important finding was clearly demonstrated by the multiparametric… More >

    Exosomes derived from osteoclasts under compression stress inhibit osteoblast differentiation

    YUE WANG, YUNFEI ZHENG*, WEIRAN LI*
    BIOCELL, Vol.45, No.2, pp. 427-444, 2021, DOI:10.32604/biocell.2021.013960
    Abstract Orthodontic tooth movement is triggered by orthodontic force loading on the periodontal ligament and is achieved by alveolar bone remodeling, which is regulated by intimate crosstalk between osteoclastogenesis and osteoblast differentiation. Whether the communication between osteoclasts and osteoblasts is influenced by orthodontic compression stress requires further clarification. In this study, osteoclasts were differentiated for 10 days. On day 4 of differentiation, the number of pre-osteoclasts peaked, as determined by the increased expression of RANK and the number of multinucleated cells. After 24 h of compression stress loading, on day 4, the number of osteoclasts increased, and the optimal magnitude of… More >
