    摘要: A method to characterize a T-cell response of a final population of T-lymphocytes resulting from the co-incubation of an initial population of T lymphocytes with a composition of antigen-presenting cells (APCs), said method comprising the steps of a) simultaneous measuring on a single cell basis at least two parameters: (i) proliferation of T lymphocytes and (ii) presence of a T cell antigen receptor on the surface of T lymphocytes and/or presence of at least one biological molecule produced by T lymphocytes, and the attribution of a positive or a negative value to each of these parameters, and b) classification of the final T-lymphocytes population into 2n different subsets of T lymphocytes, n being the number of parameters, each subset being characterized by a positive or a negative value respectively to each parameter and the determination of the proportion of T lymphocytes present in each subset with respect to the number of T lymphocytes in the final population, with said proportion being characteristic of the T-cell response. Use of the method for batch release assay and potency assay.

    摘要: An altered MHC class I determinant comprises .alpha..sub.1, .alpha..sub.2, .alpha..sub.3, .beta..sub.2 -microglobulin (.beta..sub.2 m) polypeptide domains encoded by a mammalian MHC class I locus in which the .alpha..sub.3 domain is covalently linked to the .beta..sub.2 M domain. An altered MHC class II determinant comprises .alpha..sub.1, .alpha..sub.2, .beta..sub.1, and .beta..sub.2 polypeptide domains encoded by a mammalian MHC class II locus, in which the domains are covalently linked to form a polypeptide comprising the .beta..sub.2 -.alpha..sub.2 -.alpha..sub.1 -.beta..sub.1 domains in sequence. The altered MHC class I and class II determinants can be associated with an antigen to elicit an immune response. The invention can be used in the immunization or treatment of diseases such as AIDS, multiple sclerosis, lupus erythematosus, toxic shock or snake bite.

    摘要: An altered MHC class II determinant comprises .alpha..sub.1, .alpha..sub.2, .beta..sub.1, .beta..sub.2, domains of a mammalian MHC class II locus in which the domains are covalently linked to form a construct comprising the .beta..sub.2 -.alpha..sub.2 -.alpha..sub.1 .beta..sub.1 domains in sequence. The altered class II determinants can be associated with an antigen to elicit an immune response. In addition, the altered determinants may be used to prepare antibodies. The antibodies so produced have various diagnostic and therapeutic uses.
