influenza ha

Influenza HA (110-119) refers to a specific fragment (110-119) derived from the hemagglutinin protein of the influenza virus. This fragment has the ability to induce the proliferation of Treg cells.

Influenza HA (110-119) acetate is the 110-119 fragment of influenza virus hemagglutinin that can stimulate Treg cells proliferation[1][2].

Influenza HA (518-526) is an H-2d-restricted CD8+ T cell epitope derived from the influenza virus hemagglutinin. This sequence is highly conserved across multiple H5N1, some H9N2, and certain H1N1 strains. The epitope can bind to the mouse MHC class I allele Kd to form a complex, which is subsequently recognized by specific CD8+ T lymphocytes. In influenza-infected BALB/c mice, Influenza HA (518-526) represents an immunodominant epitope that stimulates CD8+ T cells to release IFN-γ, thereby inducing a robust immune response. Currently, this epitope has been widely applied in research related to respiratory syncytial virus (RSV), influenza virus, and H5N1 influenza, among other fields.

Influenza HA (126-138) is a peptide derived from the hemagglutinin (HA) protein of the influenza virus, consisting of amino acids 126-138, and has the ability to induce apoptosis in both thymic and peripheral T-cells.

6,6′-Trehalose dioleate (6,6′-TDO) is a glycolipid extensively used for in vivo and in vitro mRNA delivery. This compound effectively encapsulates mRNA encoding hemagglutinin A (HA) from influenza A virus for use within lipid nanoparticles (LNPs), enhancing the secretion of Ifn-γ, Il-2, and Tnf-α from isolated murine spleen cells. When administered via intramuscular injection in mice, LNPs containing 6,6′-TDO predominantly accumulate in the liver and spleen. Unlike LNP formulations without 6,6′-TDO, those containing 6,6′-TDO do not reduce serum levels of blood urea nitrogen (BUN) or elevate levels of lactate dehydrogenase (LDH), troponin I, alanine aminotransferase (ALT), or aspartate aminotransferase (AST). Additionally, these LNPs enhance the serum titers of IgG1 and IgG2a antibodies in mice.

PAN endonuclease-IN-2 (compound T-31) is a PAN endonuclease inhibitor (IC50: 0.15 μM) and has antiviral properties with broad-spectrum anti-influenza activity. PAN, as the N-terminal PA subunit of the polymerase-RNA complex, possesses a cap-dependent endonuclease (CEN) active site, facilitating RNA cleavage and initiating the synthesis of new RNA molecules. PAN endonuclease-IN-2 targets both influenza HA and RdRp complexes, thereby disrupting viral entry into host cells and impeding viral replication.

It exhibits potent antiviral activity against the real A/H1N1 virus, with EC50 values of 0.92 μM for the A/H1N1 PR8 strain and 0.31 μM for the A/H1N1 Virg09 strain. VF-57 significantly inhibits cell entry of HA-mediated A/H1N1 and A/H5N1 pseudoviruses and prevents HA refolding at pH 5.2. VF-57a is utilized in IAV infection research.

Furin-IN-3 demonstrates significant antiviral activity against the influenza A virus (H7N7 strain SC35M) which relies on furin. It inhibits the cleavage and activation of viral hemagglutinin (HA), preventing the fusion of the viral membrane with the host cell membrane, thereby inhibiting viral replication and proliferation. Furin-IN-3 is useful for studying infections, such as influenza virus infection.
