  • Because of their potential for broadening vaccine-mediated protection in humans, they have been studied extensively in animals and found to be mediated predominantly by virus-specific memory T cells ( 6 , 7 ), antibodies ( 8 - 10 ), or a combination of both ( 11 - 13 ). (cdc.gov)
  • Other vaccinations include instructions for your cells to produce a germ protein. (verifiedmarketresearch.com)
  • The virus uses the spike protein to target epithelial cells by binding to the ACE2 receptor on the host cells. (springeropen.com)
  • TLR4, but Neither Dectin-1 nor Dectin-2, Participates in the Mollusk Hemocyanin-Induced Proinflammatory Effects in Antigen-Presenting Cells from Mammals. (exeter.ac.uk)
  • Research endeavors over the past several decades have identified various types of cells as suitable living drugs and versatile drug carriers. (biomedcentral.com)
  • On average, the prevalent influenza A virus strain acquires 3-4 amino acid changes per year in HA, with most being located in the regions recognized by protective antibodies. (cdc.gov)
  • Antigenic molecules, normally "large" biological polymers, usually present surface features that can act as points of interaction for specific antibodies. (wikipedia.org)
  • Herein, we evaluated the expression of Globo H and its prognostic significance in intrahepatic cholangiocarcinoma (ICC) and conducted preclinical studies to assess the antitumor activity of Globo H-specific antibody in thioacetamide (TAA)-induced ICC in rats. (bvsalud.org)
  • The most promising approaches are based on antibodies specific for the relatively conserved ectodomain of matrix protein 2 and the intersubunit region of hemagglutinin. (cdc.gov)
  • Here, we used a genomics/proteomics approach (including immunoblot experiments from pigs infected with T. suis ) to prioritize putative immunogenic excretory/secretory (E/S) proteins conserved across and specific to several gastrointestinal (GI) parasitic nematode species. (frontiersin.org)
  • A number of factors have recently contrib- a specific immune response, mediated by multiple mechanisms, uted to an increase in the attention focused on hypersensitivity including IgE antibody. (cdc.gov)
  • There has been an increase in asthma among the general review will consider protein-specific, chemical-specific, and drug- population from the mid-1960's to the mid-1990's prompting specific aspects of respiratory hypersensitivity. (cdc.gov)
  • In order to prepare our price offer for your project, please send us the name of the target protein (UniProt ortholog), or specific post-translational modification, which should be clearly recognized and/or quantified by a clonal antibody. (dbbiotech.com)
  • On the other hand, DT represents a very interesting molecular machine which allows using this protein in different bioengineering applications, such as ablation of certain cell types in transgenic mice, development of immunotoxins targeted for specific cell markers and also for delivery of certain proteins into the cytosol.
