TL;DR: The nongonadal cells in the male nematode Caenorhabditis elegans have been followed through maturation by Nomarski microscopy and this region has been reconstructed by serial section electron microscopy in order to identify the cell types that arise from known lineages.

TL;DR: Structures of the antigen binding site loops produced by nearly all the VH segments are described and it is shown that, in almost all cases, the residue patterns in the Vh segments imply that the first hyper variable regions have one of three different canonical structures and that the second hypervariable regions haveOne of five different canonical Structures.

TL;DR: Hybrid myeloma cell lines secreting monoclonal antibodies to mouse cell surface antigens have been prepared and each antigenic target was analyzed by gel electrophoresis of immunoprecipitated 125I‐labeled cell surface molecules.
Abstract: Hybrid myeloma cell lines secreting monoclonal antibodies to mouse cell surface antigens have been prepared. Spleen cells from a DA rat immunized with B10 mouse spleen cells that had been enriched for T cells were fused to cells from a nonsecreting mouse myeloma line (NSI). The presence in the culture supernatants of antibodies binding to mouse spleen cells was tested by a binding assay with 125I-labeled anti-rat IgG. From a large number of positive cultures, ten independent hybrid clones were purified, each secreting a different antibody. Each antigenic target was analyzed by (a) gel electrophoresis of immunoprecipitated 125I-labeled cell surface molecules, (b) heat stability, (c) strain and species distribution and (d) cross-inhibition of binding of different monoclonal antibodies.
It was concluded that the ten monoclonal antibodies regognized four types of antigen. One was the heterophile, heat-stable, Forssman antigen. The second (mol.wt. 210 000) appears to be a major 125I-labeled lymphoid cell surface protein. The third, a minor component of spleen cells, was precipitated as two polypeptides of mol.wt. 190 000 and 105000. Five IgG-secreting clones identify the fourth antigen, a heat-stable, possibly glycolipid component expressed on mouse red blood cells and also on thymocytes. Cross-inhibition studies suggest that these last monoclonal antibodies bind to overlapping, but not identical, determinants. The class and chain composition of the monoclonal antibodies were studied by gel electrophoresis, isoelectric focusing and ability to lyse red blood cells and thymocytes.

TL;DR: What is known about all the members of the Arf family, along with the known regulatory molecules that convert them between GDP- and GTP-bound states are reviewed.
Abstract: Small G proteins play a central role in the organization of the secre- tory and endocytic pathways. The majority of such small G proteins are members of the Rab family, which are anchored to the bilayer by C-terminal prenyl groups. However, the recruitment of some effectors, including vesicle coat proteins, is mediated by a second class of small G proteins that is unique in having an N-terminal amphipathic helix that becomes available for membrane insertion upon GTP binding. Sar1, Arf1, and Arf6 are the best-characterized members of this ADP-ribosylation factor (Arf ) family. In addition, all eukaryotes contain additional distantly related G proteins, often called Arf like, or Arls. The complete Arf family in humans has 29 members. The roles of these related G proteins are poorly under- stood, but recent work has shown that some are involved in mem- brane traffic or organizing the cytoskeleton. Here we review what is known about all the members of the Arf family, along with the known regulatory molecules that convert them between GDP- and GTP-bound states.
