Article Abstract

Background: Immunization against is important for public health. Vaccines composed of cross-reactivity antigens avoid strain-specific responses, ensuring more comprehensive protection.

Methods: The cross-reactivity between three strains from the last outbreak of in Brazil was assessed in our studies, using enzyme-linked immunosorbent assay (ELISA) and immunoblotting assays.

Results: Both assays verifed a similar humoral response between the strains evaluated. Patterns of antigen recognition differed with each dose evaluated.

Conclusions: We observed that immunization with B outer membrane vesicles (OMVs) led to the production of antibodies that recognized antigens of heterologous strains, indicating possible protection against these evaluated strains.

Treponema denticola major surface protein (Msp): a key player in periodontal pathogenicity and immune evasion.

Arch Microbiol

January 2025

Department of Stomatology, The Second Affiliated Hospital, Hengyang Medical College, University of South China, Hengyang, 421001, Hunan, China.

Treponema denticola, a bacterium that forms a "red complex" with Porphyromonas gingivalis and Tannerella forsythia, is associated with periodontitis, pulpitis, and other oral infections. The major surface protein (Msp) is a surface glycoprotein with a relatively well-established overall domain structure (N-terminal, central and C-terminal regions) and a controversial tertiary structure. As one of the key virulence factors of T.

Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.

Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.

Expression, purification and characterization of phosphatidylserine-targeting antibodies for biochemical and therapeutic applications.

Methods Cell Biol

January 2025

Department of Microbiology, Biochemistry and Molecular Genetics, (3)Center for Cell Signaling, Rutgers New Jersey Medical School, Newark, NJ, United States. Electronic address:

The externalization of Phosphatidylserine (PS) from the inner surface of the plasma membrane to the outer surface of the plasma membrane is an emblematic event during apoptosis and serves as a potent "eat-me" signal for the efferocytosis of apoptotic cells. Although less well understood, PS is also externalized on live cells in the tumor microenvironment and on live virus-infected cells whereby it serves as an immune modulatory signal that drives tolerance and immune escape. Given the importance of PS in cancer immunology and immune escape, PS-targeting monoclonal antibodies have been characterized with promising immunotherapeutic potential.

Department of Otorhinolaryngology, Shenzhen Key Laboratory of Otorhinolaryngology, Longgang Otorhinolaryngology Hospital, Shenzhen Institute of Otorhinolaryngology, No. 3004 Longgang Avenue, Shenzhen, Guangdong, China.

Background: To investigate the role of the translocase of the outer mitochondrial membrane 40 (TOM40) in oral squamous cell carcinoma (OSCC) with the aim of identifying new biomarkers or potential therapeutic targets.

Methods: TOM40 expression level in OSCC was evaluated using datasets downloaded from The Cancer Genome Atlas (TCGA), as well as clinical data. The correlation between TOM40 expression level and the clinicopathological parameters and survival were analyzed in TCGA.

In clinical practice, thymopentin (TP-5) is a commonly utilized immunomodulatory peptide drug. The relatively short half-life of TP-5, however, significantly limits its applicability in immunotherapy. Inspired by the structure of the TLR2 ligand lipopeptide Pam3CSK4, fatty acid-modified TP-5 peptides were designed and synthesized in this study.
