Eugene, OR y situadas sobre la platina del microscopio. Heterogeneity among microtubules of the cytoplasmic microtubule complex detected by a monoclonal antibody to alpha tubulin. Sustained signaling leading to T cell activation results from prolonged T cell receptor occupancy, J. Furthermore, it was carried out a quantitative analysis of conjugates containing J77 cells with CD3 clustered in the central region of centrro contact over conjugates corresponding to three independent experiments.

Basal levels of tubulin acetylation in T cells increased by treatment with such antibodies Fig. To determine whether desacetiladora activity tubulin took place at the site of contact between the T cell cfntro the host cell, tubulin acetylation was detected in the presence of TSA, a specific deacetylase inhibitor activity of fentro HDAC6, sodium butyrate and trapoxin B, two potent inhibitors of histone deacetylase activity incapable of inactivating HDAC6 Hubbert, C.

In each experiment at least cell conjugates were crntro. Exclusion of CD43 from the immunological synapse is mediated by phosphorylation-regulated relocation of the cytoskeletal adaptor moesin. Cytoskeletal polarization of T cells is regulated by an immunoreceptor tyrosine-based activation motif-dependent mechanism J. Figura 1 Figure 1. Inactivation of glycogen synthase kinase 3 promotes axonal growth and recovery in the CNS.

An object of the present invention is a method of identifying and evaluating the activity regulating compounds HDAC6 protein on T cell activation, hereinafter method of identifying compounds of the present invention, comprising the following steps: Allenspach, EJ, Cullinan, P.

These data clearly showed that could distinguish two phases during tubulin acetylation mediated superantigen. A particular object of the present invention is a method for identifying potential inhibitors of the invention where the point T i lymphocytes can be stimulated or prepared by methods known in the prior art compounds see Example ; stimulation antigen presenting cells Raji cells more SEE and transformation of cell cultures of T cells with a genetic construct allows expression of HDAC6 gene allow better assessment of the effect of such potential inhibitor compounds.

Arrowheads are directed towards the point of contact of the T cells with antigen presenting cells. Tyrosine phosphorylated T-cell receptor zeta chain associates With the actin cytoskeleton upon activation of mature T lymphocytes. Thus, the following applications have been described as therapeutic target protein derived from the functional activities involved in: Every 30 seconds series of images of fluorescence and differential interference contrast of J77 cells transfected with HDAC6 were obtained from the dentro and contacting with Raji cells pulsed with SEE.

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 lymphocytes of patients suffering from such diseases.

Also, from the results of the present invention the importance of organizaodr proteins, which act by increasing levels of tubulin acetylation observed during activation of T cells, and allow it is found: Para los experimentos de inmunoblot, 4.

The time elapsed since the initial contact time is indicated in minutes in the upper left corner of each image. By contrast, acetylation levels not varied in the presence of superantigen B Fig. The area of attachment of cytotoxic T lymphocytes to their target cells shows high motility and polarization of orgwnizador, but not myosin.

Therefore, the regulation of desacetiladora activity tubulin mediated HDAC6 and its implications for modulating the activation of T cells, disclosed herein for the first time, it can be an effective treatment for diseases associated with an immune response and also exacerbated in those that occur with a deficient immune response.
