ICAMs Are Not Obligatory for Functional Immune Synapses between Naive CD4 T Cells and Lymph Node DCs

open access: yesCell Reports, 2018
Protective immune responses depend on the formation of immune synapses between T cells and antigen-presenting cells (APCs). The two main LFA-1 ligands, ICAM-1 and ICAM-2, are co-expressed on many cell types, including APCs and blood vessels.

Structure and genetics of Escherichia coli O antigens

open access: yesFEMS Microbiology Reviews, 2019
Escherichia coli includes clonal groups of both commensal and pathogenic strains, with some of the latter causing serious infectious diseases. O antigen variation is current standard in defining strains for taxonomy and epidemiology, providing the basis ...

Systematic Chemoenzymatic Synthesis of O-Sulfated Sialyl Lewis x Antigens. [PDF]

open access: yes, 2015
O-Sulfated sialyl Lewis x antigens play important roles in nature. However, due to their structural complexity, they are not readily accessible by either chemical or enzymatic synthetic processes.

Targeting self- and foreign antigens to dendritic cells via DC-ASGPR generates IL-10-producing suppressive CD4+ T cells [PDF]

open access: yes, 2012
Dendritic cells (DCs) can initiate and shape host immune responses toward either immunity or tolerance by their effects on antigen-specific CD4(+) T cells.

Citrullinated vimentin as an important antigen in immune complexes from synovial fluid of rheumatoid arthritis patients with antibodies against citrullinated proteins [PDF]

open access: yes, 2010
Introduction: Rheumatoid arthritis (RA) is an inflammatory disease, which results in destruction of the joint. The presence of immune complexes (IC) in serum and synovial fluid of RA patients might contribute to this articular damage through different ...

Main features of DNA-based immunization vectors

open access: yesBrazilian Journal of Medical and Biological Research, 1999
DNA-based immunization has initiated a new era of vaccine research. One of the main goals of gene vaccine development is the control of the levels of expression in vivo for efficient immunization.

Rapid isolation of antigens from cells with a staphylococcal protein A-antibody adsorbent: parameters of the interaction of antibody-antigen complexes with protein A.

open access: yesJournal of Immunology, 1975
The Cowan I strain of the bacterium Staphylococcus aureus has been used as an adsorbent for antibodies complexed with radiolabeled antigens from cell lysates. This application is advanced as a superior alternative to other methods of immune precipitation

Regulation of T cell expansion by antigen presentation dynamics [PDF]

open access: yesPNAS 2019, 116 (13) 5914-5919, 2018
An essential feature of the adaptive immune system is the proliferation of antigen-specific lymphocytes during an immune reaction to form a large pool of effector cells. This proliferation must be regulated to ensure an effective response to infection while avoiding immunopathology.

CD22: A Regulator of Innate and Adaptive B Cell Responses and Autoimmunity

open access: yesFrontiers in Immunology, 2018
CD22 (Siglec 2) is a receptor predominantly restricted to B cells. It was initially characterized over 30 years ago and named “CD22” in 1984 at the 2nd International workshop in Boston (1).

Monoclonal Antibodies against the Drosophila Nervous System [PDF]

open access: yes, 1982
A panel of 148 monoclonal antibodies directed against Drosophila neural antigens has been prepared by using mice immunized with homogenates of Drosophila tissue. Antibodies were screened immunohistochemically on cryostat sections of fly heads.
