Abstract
Nicotinamide adenine dinucleotide (NAD+) serves as a critical cofactor in cellular metabolism and redox reactions. Bacterial pathways rely on NAD+ participation, where its stability and concentration govern essential homeostasis and functions. This review delves into the role and metabolic regulation of NAD+ in bacteria, highlighting its influence on physiology and virulence. Notably, we explore enzymes linked to NAD+ metabolism as antibacterial drug targets and vaccine candidates. Moreover, we scrutinize NAD+'s medical potential, offering insights for its application in biomedicine. This comprehensive assessment informs future research directions in the dynamic realm of NAD+ and its biomedical significance.

Ou J, Dong H, Luan X, Wang X, Liu Q, Chen H, Cao M, Xu Z, Liu Y, Zhao W. iTRAQ-based differential proteomic analysis of high- and low-virulence strains of Spiroplasma eriocheiris. Microb Pathog 2023; 184:106365. [PMID: 37741306 DOI: 10.1016/j.micpath.2023.106365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 09/17/2023] [Accepted: 09/18/2023] [Indexed: 09/25/2023]
Abstract
Spiroplasma eriocheiris is one of the major pathogenic bacteria in crustaceans, featuring high infectivity, rapid transmission, and an absence of effective control strategies, resulting in significant economic losses to the aquaculture industry. Research into virulence-related factors provides an important perspective to clarify how Spiroplasma eriocheiris is pathogenic to shrimps and crabs. Therefore, in this study, isobaric tags for relative and absolute quantitation (iTRAQ) technology was utilized to undertake a differential proteomic analysis of high- and low-virulence Spiroplasma eriocheiris strains at different growth phases. A total of 868 differentially expressed proteins (DEPs) were obtained, of which 31 novel proteins were identified by proteogenomic analysis. There were 62, 61, 175, and 235 DEPs between the log phase (YD) and non-log phase (YFD) of the high-virulence strain, between the log phase (CD) and non-log phase (CFD) of the low-virulence strain, between YD and CD, and between CFD and YFD, respectively. All the DEPs were compared with virulence protein databases (MvirDB and VFDB), and 68 virulence proteins of Spiroplasma eriocheiris were identified, of which 12 were involved in a total of 21 metabolic pathways, including motility, chemotaxis, growth, metabolism and virulence of the bacteria. The results of this study form the basis for further research into the molecular mechanism of virulence and physiological differences between high- and low-virulence strains of Spiroplasma eriocheiris, and provide a scientific basis for a detailed understanding of its pathogenesis.

Hijacking of Host Plasminogen by Mesomycoplasma ( Mycoplasma) hyopneumoniae via GAPDH: an Important Virulence Mechanism To Promote Adhesion and Extracellular Matrix Degradation. Microbiol Spectr 2023; 11:e0021823. [PMID: 37199643 PMCID: PMC10269845 DOI: 10.1128/spectrum.00218-23] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Accepted: 05/01/2023] [Indexed: 05/19/2023] Open
Abstract
Mesomycoplasma hyopneumoniae is the etiological agent of mycoplasmal pneumonia of swine (MPS), which causes substantial economic losses to the world's swine industry. Moonlighting proteins are increasingly being shown to play a role in the pathogenic process of M. hyopneumoniae. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), a key enzyme in glycolysis, displayed a higher abundance in a highly virulent strain of M. hyopneumoniae than in an attenuated strain, suggesting that it may have a role in virulence. The mechanism by which GAPDH exerts its function was explored. Flow cytometry and colony blot analysis showed that GAPDH was partly displayed on the surface of M. hyopneumoniae. Recombinant GAPDH (rGAPDH) was able to bind PK15 cells, while the adherence of a mycoplasma strain to PK15 was significantly blocked by anti-rGAPDH antibody pretreatment. In addition, rGAPDH could interact with plasminogen. The rGAPDH-bound plasminogen was demonstrated to be activated to plasmin, as proven by using a chromogenic substrate, and to further degrade the extracellular matrix (ECM). The critical site for GAPDH binding to plasminogen was K336, as demonstrated by amino acid mutation. The affinity of plasminogen for the rGAPDH C-terminal mutant (K336A) was significantly decreased according to surface plasmon resonance analysis. Collectively, our data suggested that GAPDH might be an important virulence factor that facilitates the dissemination of M. hyopneumoniae by hijacking host plasminogen to degrade the tissue ECM barrier. IMPORTANCE Mesomycoplasma hyopneumoniae is a specific pathogen of pigs that is the etiological agent of mycoplasmal pneumonia of swine (MPS), which is responsible for substantial economic losses to the swine industry worldwide. The pathogenicity mechanism and possible particular virulence determinants of M. hyopneumoniae are not yet completely elucidated. Our data suggest that GAPDH might be an important virulence factor in M. hyopneumoniae that facilitates the dissemination of M. hyopneumoniae by hijacking host plasminogen to degrade the extracellular matrix (ECM) barrier. These findings will provide theoretical support and new ideas for the research and development of live-attenuated or subunit vaccines against M. hyopneumoniae.

Th1 and Th17 mucosal immune responses elicited by nasally inoculation in mice with virulence factors of Mycoplasma hyopneumoniae. Microb Pathog 2022; 172:105779.

Abstract
Nicotinamide Adenine Dinucleotide-Dependent (NADH) flavin oxidoreductase and NADH oxidase (NOX) are important virulence factors of Mycoplasma hyopneumoniae (Mhp), which are devoted to the function of adhesion, oxidative stress damage and apoptosis to host cells in our previous studies. Here, immune responses of NADH flavin oxidoreductase (NFOR) and NOX in mice and immune efficacy inoculated with intramuscular (IM), intranasal (IN), intramuscular unite intranasal (IM + IN) approaches were evaluated and compared. Cellular immunity levels, systemic immune and local mucosal immune responses were investigated by indirect enzyme-linked immunosorbent assay (iELISA) and quantitative reverse transcription PCR (qRT-PCR). Mice inoculated with NFOR and NOX by IM and IN or IM + IN could induce obvious secretion of specific immunoglobulin G (IgG) and secretory immunoglobulin A antibodies (sIgA) compared to those in negative control group. IM + IN inoculation resulted in systemic and local mucosal immune responses that were strongly produced. Moreover, Mhp NFOR and NOX could activate local mucosal immune responses mediated by Th1 and Th17 cells by IN. Our finding supported the notion that IM + IN was an effective immunization route for Mhp, which lays a foundation for more effective prevention of Mhp, and provides theoretical basis for the development of new subunit vaccines of Mhp.
