Suppression of Pathological Allergen-Specific B Cells by Protein-Engineered Molecules in a Mouse Model of Chronic House Dust Mite Allergy.

Der p1 is one of the major allergens causing house dust mite (HDM) allergy. Pathological Der p1-specific B cells play a key role in allergic inflammation as producers of allergen-specific antibodies. Crosslinking the inhibitory FcγRIIb with the B cell receptor triggers a high-affinity suppressive signal in B cells.

Targeting the Progression of Lupus-Like Disease in Humanized Mouse Model by Specific Dietary Components.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease with a number of immunological aberrations in the mechanisms of innate and adaptive immune responses. Spontaneous and induced mouse models of the disease have contributed significantly to the advancement in lupus treatments. The involvement of humanized models, engrafted with lupus patients' immune cells, represented the possibility to study the development of SLE.

Design, Development and Immunogenicity Study of a Multi-Epitope Vaccine Prototype Against SARS-CoV-2.

SARS-CoV-2 caused the COVID-19 pandemic, which overwhelmed global healthcare systems. Over 776 million COVID-19 cases and more than 7 million deaths were reported by WHO in September 2024. COVID-19 vaccination is crucial for preventing infection and controlling the pandemic.

Modified Hemocyanins from and Exhibit Strong Antitumor Activity in the B16F10 Mouse Melanoma Model.

Melanoma is one of the most common tumors worldwide, and new approaches and antitumor drugs for therapy are being investigated. Among the promising biomolecules of natural origin for antitumor research are gastropodan hemocyanins-highly immunogenic multimeric glycoproteins used as antitumor agents and components of therapeutic vaccines in human and mouse cancer models. A murine melanoma model established in C57BL/6 mice of the B16F10 cell line was used to study anticancer modified oxidized hemocyanins (Ox-Hcs) that were administered to experimental animals (100 μg/mouse) under different regimens: mild, intensive, and with sensitization.

Cytokine Signatures and Immune Dysregulation in COVID-19 Patients: Transcriptomic and Serum Analysis.

COVID-19, caused by the SARS-CoV-2 virus, has caused a global health crisis, necessitating a deeper understanding of its pathophysiology. In this study, we explored the immune and hematological dynamics in COVID-19 patients to gain insights into disease severity and prognosis. Our findings revealed distinct cytokine profiles in moderate and severe cases.
