Figura 5 Figure 5.

In each experiment at least cell conjugates were counted. The area of attachment of cytotoxic T lymphocytes to their target cells shows high motility and polarization of actin, but not myosin. Se muestra un experimento representativo de tres.

To confirm that the increase in microtubule acetylation took place on T cells, the effect it had on microtubule acetylation CD3 crosslinking by monoclonal antibodies directed to this molecule was examined. Figura 2 Figure 2.

Eugene, OR y situadas sobre la platina del microscopio.

A representative experiment of three is shown. HDAC6 deacetylase activity links the tubulin cytoskeleton with immune synapse organization. The development of these methods is based on the regulation of the levels of tubulin acetylation using HDAC6 tubulin deacetylase as a therapeutic target.

This definition also includes those compounds or molecules that increase expression of the gene encoding the protein HDAC6. M LeDizet Piperno G. Furthermore, the source of these organizado compounds, inhibitors or agonists of the activity of proteins HDACs can be varied, so that can be natural e.

Citoesqueleto – Wikipedia, a enciclopedia libre

After recognizing the antigen, the T cell reorients the microtubule organizing center MTOC towards antigen-presenting cell as a result of the organization and maturation of the immune synapse Podack ER, and Kupfer, A. The object of the present invention is a method of identifying and evaluating the activity regulating compounds HDAC6 protein on T cell activation, comprising the following steps: Los marcadores de peso molecular se indican a la izquierda.

Cytoskeletal polarization of T cells is regulated by an immunoreceptor tyrosine-based activation motif-dependent mechanism J. Use of compounds that regulate hdac6 tubulin deacetylase activity in the preparation of pharmaceutical compositions, method of identifying the aforementioned regulating compounds, said pharmaceutical compounds and applications thereof.

TCR engagement induces proline-rich tyrosine kinase-2 Pyk2 translocation to the T cell-APC interface independently of Pyk2 activity and in an immunoreceptor tyrosine-based activation motif-mediated fashion.

In this regard, the gene transfer technology could, by viral vectors, gene be useful in therapy to express tissue-specific manner HDAC6 enzyme in T microtunulos of patients suffering from such diseases. M Ribeiro et al. The membrane-microfilament linker ezrin is involved in the formation of the immunological synapse and in T cell activation. Three-dimensional supramolecular activation clusters of seggregation in T cells.

J77 and Raji cells were contacted in the presence of SEE or SEB for the indicated times, and then the levels of acetylated tubulin and tubulin by immunoblot under nonreducing conditions were detected.

Dynamic polarization of the microtubule cytoskeleton during CTL-mediated killing.

El anticuerpo policlonal fue cedido generosamente por el Dr. In vivo destabilization of microtubules by dynamic HDAC6-mediated deacetylation. Figura 4 Figure 4. Then the cell conjugates fixed, permeabilized and stained for acetylated tubulin. Asterisks indicate the location of Raji cells in cell conjugates. Then the cell conjugates were gently resuspended and plated on PLL coated coverslips for 15 min as previously described Sancho et al.

Immunoprecipitation was carried out similarly to as previously described Sancho, D. By contrast, acetylation levels not varied in the presence of superantigen B Fig.

Asterisks denote Raji cells. Thus, an object of the present invention is the use of a compound or regulating agent, inhibitor or activator of the activity of HDAC6 protein, hereinafter use of a compound of the present invention, in preparing medicaments or pharmaceutical compositions for the treatment of diseases, disorders or diseases of mammals, preferably human, that develop with alterations of the immune system, preferably with the activation of T cells altered.

Nature Then the cells were fixed, permeabilized and stained for HDAC6 and acetylated tubulin. Date of ref document: Cell Biol 95, ; The immunological synapse and the actin cytoskeleton: They were counted at least conjugates by experiment. The amount of acetylated microtubules was greater in specific superantigen conjugates that conjugates between cells of the same type or cell conjugates established in the absence of superantigen E Fig.

Activation of T cells by antigen also involves translocation microtubule organizing center MTOC and the Golgi apparatus to the site of contact with antigen presenting cell and the production of IL-2 Geiger, B.
