Immuno-reactivity evaluation of Mce-truncated subunit candidate vaccine against Mycobacterium avium subspecies paratuberculosis challenge in the goat models. BMC Vet Res 2023; 19:157. [PMID: 37710242 PMCID: PMC10500891 DOI: 10.1186/s12917-023-03715-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 09/01/2023] [Indexed: 09/16/2023] Open
Abstract
BACKGROUND Detection of an appropriate antigen with high immunogenicity can be a big step in the production of an effective vaccine for control of Johne's disease (JD). The aim of this study was to evaluate the efficacy of Mce-truncated protein as a subunit vaccine candidate for the control of JD in experimentally challenged goats. MATERIALS AND METHODS Six healthy goat kids were immunized with Mce-truncated protein, and two goats were kept as controls. All kids were twice challenged orally with live Mycobacterium avium subspecies paratuberculosis(MAP) strain and half the goats from both the categories were sacrificed at 7 and 10 months after start of challenge study. Culture of MAP was performed from all the necropsied tissues to determine the true JD infection status. RESULTS Mce-truncated protein only reacted with pooled vaccinated goat sera in western-blot. A significant increase in humoral immune response against Mce protein was also observed in vaccinated goats. Compared to the control group, vaccinated goats gained higher body weights and none of them shed MAP or showed histopatological lesions or colonization of MAP in their necropsy tissues. CONCLUSIONS The new Mce protein based vaccine provided significant immunity in goats as they could meet the challenge with live MAP bacilli. Although the vaccine used in this study showed the high potential as a new effective vaccine for the control of JD, further validation study is still required to successfully implement the vaccine for JD control program.

Abstract
Apolipoprotein E (ApoE) is a lipid-binding protein with ε2, ε3, and ε4 allelic variants in human. The ε4 isoform (ApoE4) is the strongest genetic risk factor for the late-onset form of Alzheimer's disease (AD), and is also associated with multiple neurological disorders, multiple sclerosis, and cerebrovascular disease. Here, induced pluripotent stem cells were derived from the peripheral blood mononuclear cells of a 70-year-old male donor with APOE-ε4/ε4 alleles background to explore pathogenesis and screen potential treatment methods in neurodegenerative diseases. In the newly-developed induced pluripotent stem cell line, the pluripotent markers were well expressed. In addition, the generated cells displayed a normal karyotype and have differentiation potential.

Abstract
Potocki-Lupski syndrome (PTLS; MIM 610883) is a neurodevelopmental disorder associated with a 3.7 Mb copy number variant (CNV) duplication, locating in chromosome 17p11.2. (Soler-Alfonso et al., 2011). Here, a human induced pluripotent stem cell (iPSC) line was derived from the peripheral blood mononuclear cells of a 5-year-old child suffering Potocki-Lupski syndrome. The generated iPSCs were integration-free, had the 17p11.2 3.7 Mb CNV duplication with no additional genomic alterations, a stable karyotype, expressed pluripotency stem cell markers and could differentiate towards the three germ layers in vitro. Patient's derived iPSCs are a valuable resource for in vitro modeling of 17p11.2 microduplication induced Potocki-Lupski syndrome.

Feature of Adhesins Produced by Human Clinical Isolates of Mycobacterium intracellulare, Mycobacterium intracellulare subsp. chimaera and Closely Related Species. Microorganisms 2020; 8:microorganisms8081154. [PMID: 32751435 PMCID: PMC7465531 DOI: 10.3390/microorganisms8081154] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 07/29/2020] [Accepted: 07/29/2020] [Indexed: 01/09/2023] Open
Abstract
The Mycobacterium avium complex includes two closely related species, Mycobacterium avium and Mycobacterium intracellulare. They are opportunistic pathogens in humans and responsible for severe disease in a wide variety of animals. Yet, little is known about factors involved in their pathogenicity. Here, we identified, purified and characterized adhesins belonging to the heparin-binding hemagglutinin (HBHA) and laminin-binding protein (LBP) family from M. intracellulare ATCC13950 and examined clinical isolates from patients with different pathologies associated with M. intracellulare infection for the presence and conservation of HBHA and LBP. Using a recombinant derivative strain of M. intracellulare ATCC13950 producing green fluorescent protein and luciferase, we found that the addition of heparin inhibited mycobacterial adherence to A549 cells, whereas the addition of laminin enhanced adherence. Both HBHA and LBP were purified by heparin-Sepharose chromatography and their methylation profiles were determined by mass spectrometry. Patients with M. intracellulare infection mounted strong antibody responses to both proteins. By using PCR and immunoblot analyses, we found that both proteins were highly conserved among all 17 examined clinical M. intracellulare isolates from patients with diverse disease manifestations, suggesting a conserved role of these adhesins in M. intracellulare virulence in humans and their potential use as a diagnostic tool.

Induced pluripotent stem cell (iPSC) line (HEBHMUi002-A) from a healthy female individual and neural differentiation. Stem Cell Res 2019; 42:101669.

Abstract
Induced pluripotent stem cells (iPSCs) can be used to generate different types of somatic cells in vitro, including neuronal cells. Here, a human iPSC line was generated from the peripheral blood mononuclear cells of a healthy 39-year-old individual. The resulting iPSCs were integration-free, maintained the normal karyotype, expressed pluripotency stem cell markers, and were demonstrated to be capable of differentiating into cells representative of the three embryonic germ layers. Furthermore, we showed that this iPSC line could be differentiated into neural stem cells. Taken together, this generated iPSC line could be useful to test multiple differentiation protocols, and also serve as a control for investigating drug development and disease mechanisms.
