Recently, we reported that the type 6 secretion system (T6SS) of Aeromonas hydrophila SSU plays an important role in bacterial virulence in a mouse model, and immunization of animals with the T6SS effector haemolysin co-regulated protein (Hcp) protected them against lethal infections with wild-type bacteria. Additionally, we showed that the mutant bacteria deleted for the vasH gene within the T...
Objective(s): The periodic binding of protein expressed by Mycobacterium tuberculosis H37Rv with the host cell receptor molecules i.e. fibronectin (Fn) is gaining significance because of its adhesive properties. The genome sequencing of M. tuberculosis H37Rv revealed that the proline-glutamic (PE) proteins contain polymorphic GC-rich repetitive sequences (PGRS) which have clinical importance i...
Background: Existence of bacterial host cell DNA contamination in biopharmaceutical products is a potential risk factor for patients receiving these drugs. Hence, the quantity of contamination must be controlled under the regulatory standards. Although different methods such as hybridization assays have been employed to determine DNA impurities, these methods are labor, intensive and rather exp...
Recent advances in mammalian cell culture processes have significantly increased product titers, but have also resulted in substantial increases in cell density and cellular debris as well as process and product related impurities. As such, with improvements in titer, corresponding improvements in downstream processing are essential. In this study we have developed an alternative antibody harve...
General Bovine serum albumin, bovine carbonic anhydrase, and conalbumin were purchased from Sigma-Aldrich. Lactoferrin was obtained from Glanbia Nutritionals, Inc. Monoclonal antibody, mAbX, was overproduced in a Chinese hamster ovary (CHO) cell culture and previously purified by column chromatographic methods. Protein fractions were analyzed by SDS-PAGE using Criterion Tris-HCl 4–20% linear gr...
Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...
To learn more about holocentric chromosome structure and function, we generated a monoclonal antibody (mAb), 6C4, that recognizes the poleward face of mitotic chromosomes in Caenorhabditis elegans. Early in mitosis, mAb 6C4 stains dots throughout the nucleoplasm. Later in prophase, mAb 6C4 stains structures on opposing faces of chromosomes which orient towards the centrosomes at metaphase. Colo...
conclusions the data indicate that esat6-cfp10 could support the survival of m. tuberculosis in the host through altering the host immune response. it also indicates that the host may gain some level of protection from a second exposure to m. tuberculosis, as evidenced by increased proliferation of nr8383-ec. background mycobacterium tuberculosis is the major pathogen of tuberculosis, which aff...
Coronavirus Disease 2019 (COVID-19) is a viral pneumonia emerged in December 2019 in Wuhan, China. Its cause is a new virus from the coronavirus family scientifically named Coronavirus Acute Respiratory Syndrome 2 (SARS-CoV-2). In this review study, articles published in English until March 23, 2020 on new coronavirus infection were reviewed. These articles are obtained by searching in PubMed, ...
