The immunoglobulin M (IgM) antibody isotype, distinguished by its substantial size, boasts unique characteristics including extensive glycosylation and oligomerization. To characterize its properties, overcoming the difficulty of producing well-defined multimers is essential. In this report, we demonstrate the expression of two SARS-CoV-2 neutralizing monoclonal antibodies from glycoengineered plant sources. A shift from IgG1 to IgM antibody production yielded IgMs, formed from the precise assembly of 21 human protein subunits into pentamers. The four recombinant monoclonal antibodies demonstrated a highly consistent and reproducible human-type N-glycosylation pattern, each containing only one dominant N-glycan species at each glycosylation site. Pentameric IgMs displayed a substantial enhancement in antigen binding and viral neutralization, reaching up to 390 times the potency of the parental IgG1. A synthesis of these results might alter forthcoming vaccine, diagnostic, and antibody therapy designs, underscoring the diverse applications of plants in expressing complex human proteins, equipped with precise post-translational modifications.
The development of an effective immune response is essential for the success rate of mRNA-based therapeutics. see more A novel nanoadjuvant system, QTAP, was created using Quil-A and DOTAP (dioleoyl 3 trimethylammonium propane) for the purpose of effectively delivering mRNA vaccine constructs into cells. Electron microscopy confirmed the creation of nanoparticles from the complexation of mRNA with QTAP, having an average size of 75 nanometers and approximately 90% encapsulation. Modified mRNA, incorporating pseudouridine, demonstrated enhanced transfection efficiency and protein production with reduced toxicity compared to the unmodified mRNA. Macrophage exposure to QTAP-mRNA or just QTAP resulted in an increase in the activity of pro-inflammatory pathways such as NLRP3, NF-κB, and MyD88, a marker of macrophage activation. In C57Bl/6 mice, nanovaccines based on QTAP technology, carrying Ag85B and Hsp70 transcripts (QTAP-85B+H70), effectively induced potent IgG antibody responses and IFN-, TNF-, IL-2, and IL-17 cytokine production. An aerosol challenge using a clinical isolate, specifically M. avium subspecies, was conducted. The lungs and spleens of immunized animals (M.ah) demonstrated a significant reduction in mycobacterial counts, as assessed at both four and eight weeks following the challenge. Diminished M. ah levels were observed in conjunction with decreased histological lesions and a robust cellular immune response, as predicted. At eight weeks post-challenge, a notable presence of polyfunctional T-cells expressing IFN-, IL-2, and TNF- was observed; however, no such cells were identified at four weeks. A key finding from our analysis is that QTAP is a highly efficient transfection agent that may elevate the immunogenicity of mRNA vaccines designed to combat pulmonary Mycobacterium tuberculosis infections, an important public health concern particularly for the elderly and immunocompromised.
Because altered microRNA expression significantly impacts tumor development and progression, microRNAs hold promise as novel therapeutic targets. Overexpression of miR-17, a characteristic onco-miRNA, is observed in B-cell non-Hodgkin lymphoma (B-NHL), possessing distinctive clinical and biological characteristics. AntagomiR molecules, despite extensive study for suppressing the regulatory roles of overactive onco-miRNAs, face significant clinical hurdles due to their rapid degradation, renal clearance, and poor cellular internalization when administered as bare oligonucleotides.
To address the difficulties involved, we used CD20-targeted chitosan nanobubbles (NBs) to safely and preferentially deliver antagomiR17 to B-NHL cells.
For the encapsulation and targeted release of antagomiRs into B-NHL cells, positively charged 400 nm-sized nanobubbles serve as a stable and effective nanoplatform. Within the tumor microenvironment, NBs accumulated rapidly, but only those that were conjugated with a targeting system, such as anti-CD20 antibodies, were taken up by B-NHL cells, causing the release of antagomiR17 into the cytoplasm.
and
In the human-mouse B-NHL model, a decrease in miR-17 levels correlated with a reduction in tumor mass, with no documented instances of adverse effects.
Anti-CD20 targeted NBs, the subject of this study, demonstrated the required physical-chemical properties and stability, proving suitable for the delivery of antagomiR17.
By modifying their surfaces with specific targeting antibodies, these nanoplatforms offer a promising strategy for addressing B-cell malignancies and other cancers.
This study investigated anti-CD20 targeted nanobiosystems (NBs), which exhibited suitable physicochemical and stability properties for antagomiR17 delivery in vivo. These nanobiosystems represent a valuable nanoplatform for addressing B-cell malignancies or other cancers through modification of their surface with specific targeting antibodies.

The degenerative joint condition, osteoarthritis, which is non-inflammatory, further compromises the mobility of older adults. Osteoarthritis's molecular mechanisms are yet to be fully understood. Ubiquitination, a particular form of post-translational modification, has demonstrated a potential impact on osteoarthritis's development and progression, either accelerating or improving it, through targeting specific proteins for ubiquitination. This action also determines the protein stability and localization. Deubiquitination, facilitated by deubiquitinases, effectively reverses the ubiquitination process. This review concisely summarizes the current state of knowledge about the multiple roles that E3 ubiquitin ligases play in the onset and progression of osteoarthritis. We further elucidate the molecular understanding of deubiquitinases' role in osteoarthritis pathogenesis. Additionally, our analysis highlights numerous compounds that specifically affect E3 ubiquitin ligases and deubiquitinases, directly influencing osteoarthritis progression. We explore the obstacles and prospective avenues within osteoarthritis treatment, focusing on modulating the expression of E3 ubiquitin ligases and deubiquitinases to boost therapeutic efficacy. We believe that influencing ubiquitination and deubiquitination activities has the potential to curb the advancement of osteoarthritis, ultimately optimizing treatment results for individuals.
Chimeric antigen receptor T cell therapy has emerged as a vital immunotherapeutic tool, facilitating the advancement of cancer treatment. CAR-T cell therapy's effectiveness in solid tumors is constrained by the complexity of the tumor microenvironment and the presence of immune checkpoints that exert an inhibitory effect. Tumor cell annihilation is hampered by the TIGIT immune checkpoint, an entity on T cells which binds to CD155, a marker residing on the surface of tumor cells. The approach of inhibiting the interaction of TIGIT and CD155 displays promising potential in cancer immunotherapy. Anti-MLSN CAR-T cells and anti-TIGIT were utilized in concert in this study for the therapeutic approach to solid tumors. In vitro studies demonstrated that the addition of anti-TIGIT treatment markedly boosted the killing capabilities of anti-MLSN CAR-T cells against target cells.
