The invention concerns the use of a eukaryotic cell coding for at least an HLA-G isoform, to obtain an immunomodulating medicine for inhibiting the activity of killer cells, in particular NK cells and/or for inhibiting the primary allogenic response, in parthologies or situations in which the ...

The distinguishing feature of the cilium is theaxoneme. The axoneme is a microtubule-based extension that protrudes from the apical surface of the cell (Fig. 1D). The axoneme is made up of nine sets of microtubule doublets extending from the basal body. The organization of axonemal microt...
One unique example of RNA processing is the protein-catalysed splicing of transfer RNAs (tRNAs), an essential step during tRNA maturation (Phizicky et al. 1992). Intron-containing tRNA genes are found in all three kingdoms of life. However, the biochemical strategies for tRNA splicing differ ...
This allows the identification of the repertoire of possible PDIs at these DNA regions rather than binding events occurring in a specific condition or cell type. However, as each arrayed yeast strain only expresses one TF, eY1H assays typically cannot identify heterodimer-DNA interactions or other...
Virtually all eukaryotic cells contain spatially distinct genomes, a single nuclear genome that harbours the vast majority of genes and much smaller genomes found in mitochondria present at thousands of copies per cell. To generate a coordinated gene response to various environmental cues, the genomes...
What is an example of an agranulocyte? agranulocyteAny white blood cell(see leucocyte) with a nongranular cytoplasm and a large spherical nucleus; lymphocytes and monocytes are examples. Agranulocytes are produced either in the lymphatic system or in the bone marrow and account for 30% of all...
The prep room. Quiz 2: Key 1) 100g = _0.1___kg 2) 24.62kg=__246,200___dg 3) Bacteria are single-celled ___prokaryotes___ (prokaryotes or eukaryotes). 4) An example of a heterotrophic Protista is: a) Algae b) Amoeba c) Mushroom d) Human 5) Which of the following is the...
Ribosomes are universally conserved enzymes that carry out protein biosynthesis. Bacterial and eukaryotic ribosomes, which share an evolutionarily conserved core, are thought to have evolved from a common ancestor by addition of proteins and RNA that bestow different functionalities to ribosomes from dif...
