File Description [top]

Science, published by the American Association for the Advancement of Science (AAAS), serves its readers as a forum for the presentation and discussion of important issues related to the advancement of science. Emphasis is on material pertaining to the interactions among science, technology, government, and society. The peer-reviewed section of the journal presents cutting-edge research of either interdisciplinary interest or unusual significance to the specialist. Topical coverage reflects the range of AAAS’s interest across the physical, biological, and social sciences. Major sections of the journal are This Week in Science, News and Comments, Research News, Articles, Research Articles, and Reports. Science also includes book reviews, editorial and letters sections, policy forums, perspectives, and information about new techniques and instrumentation.

          CD1 molecules are distant cousins of major histocompatibility complex 
    (MHC)  molecules;  both  are  located on the cell surface, and MHC binds or 
    "displays"  foreign  peptides  so  that the immune system can recognize and 
    eliminate  them.  In  their  Perspective,  Brenner and Porcelli discuss the 
    crystal  structure of CD1 , reported by Zeng et al . in this issue. The new 
    work  shows  how the structure of CD1 is specialized for presenting another 
    class of antigens-lipids.

  /TX  Text:    IMMUNOLOGY: 
     Update: Antigen Presentation: A  Balanced Diet 
         Michael Brenner and  Steven Porcelli 
          For  much  of  the past decade, immunologists studying how the immune 
    system   recognizes   foreign  molecules  have  focused  on  the  molecular 
    mechanisms  by  which  T  cells  recognize  peptide  antigens.  A series of 
    landmark  crystallographic  studies  have revealed how peptide antigens are 
    displayed  on  the  surface of cells. Amino acid side chains of the peptide 
    are  anchored  into  specific pockets in the peptide binding grooves of the 
    major  histocompatibility  complex  (MHC)  class  I  and  class II membrane 
    proteins.  This  determines  which  peptides  can  bind MHC, and thus which 
    peptides  have the potential to be recognized by T cell receptors. However, 
    several remarkable findings suggest that an important part of the story has 
    not  yet  been  told.  On  page 339 of this issue, Zeng et al . present the 
    three-dimensional  structure  of murine CD1d1, a representative of a family 
    of  conserved  mammalian proteins that are distant cousins of MHC molecules 
    (1) (see figure). This structure reinforces the view that CD1 proteins bind 
    and  present antigen in a way that offers T cells a fundamentally different 
    look  at the antigenic universe, one that includes lipids and glycolipids.
