The possible pathways for realization of antiviral activity of interferon inducer poly (I).poly(C) have been studied. The stimulating effect of interferon inducer on the net protein synthesis in human M19 fibroblasts has been demonstrated. Compositions of the specific proteins induced by poly(I).poly(C) or interferon in human M19 fibroblasts and in monkey cells 4647 have been analyzed by electrophoresis technique. The data obtained suggest the existence of common gene products for interferon and ds-inducer. The ds-inducer requires the synthesis of lesser amounts of proteins for realization of its biological activity as compared with interferon.

Background: Psoriasis is an immune-related inflammatory systemic condition characterized by dysregulated keratinocyte proliferation and chronic inflammation. Tanshinone I (Tan-I) has recently been discovered to have immunomodulatory properties, but its role and mechanisms in treating psoriasis remain unclear.
Objective: To evaluate the efficacy of Tan-I in the treatment of psoriasis and to determine the mechanisms involved.

Background: In clinical practice, imiquimod is used to treat Human Papillomavirus (HPV)-related lesions, such as condyloma and Cervical Intraepithelial Neoplasia (CIN). Metronidazole is the most commonly prescribed antibiotic for bacterial vaginosis. The study developed biodegradable imiquimod- and metronidazole-loaded nanofibrous mats and assessed their effectiveness for the topical treatment of cervical cancer, a type of HPV-related lesion.

Background: Lung cancer, particularly non-small cell lung cancer (NSCLC), has high recurrence rates and remains a leading cause of cancer-related death, despite recent advances in its treatment. Emerging therapies, such as chimeric antigen receptor (CAR)-T cell therapy, have shown promise but face significant challenges in targeting solid tumors. This study investigated the potential of combining receptor tyrosine kinase-like orphan receptor 1 (ROR1)-targeting CAR-T cells with ferroptosis inducers to promote ferroptosis of tumor cells and enhance anti-tumor efficacy.

Dealing with infections is a daily challenge for wild animals. Empirical data show an increase in reactive oxygen species (ROS) production during immune response. This could have consequences on telomere length, the end parts of linear chromosomes, commonly used as proxy for good health and ageing.

Human metapneumovirus (HMPV) is an important causative agent of respiratory tract disease. Fundamental knowledge of the interaction between HMPV and the innate immune system could lead to the design of novel antiviral therapies. Previously, we demonstrated that HMPV M2-2 deletion mutants had hypermutated genomes and contained defective interfering particles (DIs), which are potent inducers of the IFN response.
