Many viruses have evolved mechanisms to avoid detection by the host immune system. Herpes simplex virus (HSV) expresses an immediate early protein, ICP47, which blocks presentation of viral peptides to MHC class I-restricted cells. The properties of the newly synthesized class I molecules in HSV-infected cells resemble those of cell lines deficient in the(More)
The study of the effects of cytomegaloviruses on the MHC class I-restricted antigen presentation pathway has yielded an embarrassment of riches. The human cytomegalovirus (HCMV) encodes at least five to six different glycoproteins, each interfering in a different way with elimination of the virus by the host immune system. Most likely, it is the concerted(More)
Herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) express an immediate-early protein, ICP47, that effectively inhibits the human transporter associated with antigen presentation (TAP), blocking major histocompatibility complex (MHC) class I antigen presentation to CD8+ T cells. Previous work indicated that the mouse TAP is relatively resistant to(More)
Polyclonal (PAT) and monoclonal (AXO 49) antibodies against Paramecium axonemal tubulin were used as probes to reveal tubulin heterogeneity. The location, the nature and the subcellular distribution of the epitopes recognized by these antibodies were, respectively, determined by means of: (i) immunoblotting on peptide maps of Paramecium, sea urchin and(More)
MDCK cells form a polarized epithelium when they reach confluence in tissue culture. We have previously shown that concomitantly with the establishment of intercellular junctions, centrioles separate and microtubules lose their radial organization (Bacallao, R., C. Antony, C. Dotti, E. Karsenti, E.H.K. Stelzer, and K. Simons. 1989. J. Cell Biol.(More)
Incorporation of Paramecium axonemal tubulin into lysed endosperm cells of the higher plant Haemanthus enabled us to identify sites of microtubule assembly. This exogenous Paramecium tubulin could be traced by specific antibodies that do not stain endogenous plant microtubules. Intracellular copolymerization of protozoan and higher plant tubulins gave rise(More)
Microtubule (MT) dynamics in PtK2 cells have been investigated using in vivo injection of unmodified Paramecium ciliary tubulin and time-lapse fixation. The sites of incorporation of the axonemal tubulin were localized using a specific antibody which does not react with vertebrate cytoplasmic tubulin (Adoutte, A., M. Claisse, R. Maunoury, and J. Beisson.(More)
This paper is in response to the question 'ASIC Design the nm era - dead or alive' from an ASIC library architecture and library flow point of view. The authors believe it is certainly significantly harder to design in the nm era but ASIC design is not dead. ASIC Design is much more challenging in the nanometer era. This paper will present some of the main(More)
In combinational logic circuits, a single switching event on the primary inputs may give rise to multiple switchings at the internal nodes. This glitching effect is caused primarily by unequal delay paths and results in increased power consumption and decreased device reliability. In this paper, we present a new algorithm to estimate the maximum number of(More)
