Synthetic antisense peptides encoded in the antisense strands of DNA corresponding to the 1-14, 42-54 and 103-115 fragments of the human interferon-beta sequence were applied in the purification of recombinant human interferon-beta from a mammalian cell culture. The protein fragments were selected on the basis of their computer-predicted exposure on the surface of the protein. The antisense peptides were synthetized by the solid-phase method directly on the resin used as the stationary phase in affinity chromatography. All the tested antisense peptides showed a selective affinity for human interferon-beta, permitting a ten-fold purification of the protein.

Stimulator of interferon genes (STING) agonists have been developed and tested in clinical trials for their antitumor activity. However, the specific cell population(s) responsible for such STING activation-induced antitumor immunity have not been completely understood. In this study, we demonstrated that endothelial STING expression was critical for STING agonist-induced antitumor activity.

Currently, no approved antiviral drugs target dengue virus (DENV) infection, leaving treatment reliant on supportive care. DENV vaccine efficacy varies depending on the vaccine type, the circulating serotype, and vaccine coverage. We investigated defective interfering particles (DIPs) and lipid nanoparticles (LNPs) to deliver DI290, an anti-DENV DI RNA.

Congenital intracranial hemangiomas are rare benign vascular tumors that develop before birth. Although various treatments, including surgery, steroids, interferon-α, thalidomide, bevacizumab, or propranolol, have been reported, no standard therapy has been established. We report the case of a neonate with congenital intracranial hemangioma and central nervous system symptoms requiring therapeutic intervention.

Background And Objective: Asthma-COPD overlap (ACO) is characterized by patients exhibiting features of both asthma and COPD. Currently, there is no specific treatment for ACO. This study aimed to investigate the therapeutic potential of targeting CD131, a shared receptor subunit for IL-3, IL-5 and GM-CSF, in ACO development and in preventing acute viral exacerbations.

Background: Ulcerative colitis (UC), an inflammatory disease characterized by intestinal barrier dysfunction, poses significant challenges because of the toxicity and adverse effects commonly associated with conventional therapies. Safer and more efficacious treatment strategies are needed.

Purpose: The purpose of this study was to treat UC with Folium Artemisiae Argyi exosome-like nanovesicles (FAELNs) and to explore its related mechanism to provide a safer and more effective means for the treatment of ulcerative colitis.
