New vaccine technologies are needed to combat many existing infections and prepare better for those that may emerge in the future. The conventional technologies that rely on protein-based vaccines are still severely restricted by the sparsity and poor accessibility of available adjuvants. One possible solution to this problem is to enhance antigen immunogenicity by a more natural means by complexing it with antibodies in the form of immune complexes (ICs). However, natural ICs are impractical as vaccines, and significant research efforts have been made to generate them in recombinant form, with plant bioengineering being at the forefront of these efforts. Here, we describe the challenges and progress made to date to make recombinant IC vaccines applicable to humans.

Ovarian cancer (OvCa) is the most lethal gynaecology malignancies worldwide. Neutrophil extracellular traps (NETs), net-like protein structures produced by activated neutrophils and DNA-histone complexes, have a central role in tumours, though haven't been fully explored in OvCa. We obtained transcriptome data from TCGA-OvCa database (n = 376) as training, ICGC-OvCa database (n = 111) as validation and GTEx database (n = 180) as controls.

Lung cancer is the most common type of cancer diagnosed worldwide and is also among the most fatal. Early detection, before symptoms become evident, is fundamental for patients' survival. Therefore, several lung cancer biomarkers have been proposed to enable a prompt diagnosis, including neuron-specific enolase (NSE) and carcinoembryonic antigen (CEA).

The bacterium responsible for Lyme disease, , accumulates high levels of manganese without iron and possesses a polyploid genome, characteristics suggesting potential extreme resistance to radiation. Contrary to expectations, we report that wild-type B31 cells are radiosensitive, with a gamma-radiation survival limit for 10 wild-type cells of <1 kGy. Thus, we explored radiosensitivity through electron paramagnetic resonance (EPR) spectroscopy by quantitating the fraction of Mn present as antioxidant Mn metabolite complexes (H-Mn).

Bovine viral diarrhea virus (BVDV) is a significant pathogen that exerts substantial economic influence on the global cattle industry. Developing a safe and effective novel vaccine targeting various BVDV subtypes is critical for controlling BVDV infection. In the study, we created two distinct multi-epitope vaccines by linking highly conserved and dominant cytotoxic T-lymphocytes (CTL), helper T-lymphocytes (HTL), and B-cell epitopes from either the E0 or E2 envelope glycoprotein of diverse BVDV subtypes.

Viral proteases play critical roles in the host cell and immune remodeling that allows virus production. The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) papain-like protease (PLpro) encoded in the large nonstructural protein 3 (Nsp3) also possesses isopeptidase activity with specificity for ubiquitin and ISG15 conjugates. Here, we interrogated the cellular interactome of the SARS-CoV-2 PLpro catalytic domain to gain insight into the putative substrates and cellular functions affected by the viral deubiquitinase.
