A transgenic non-human animal, such as a mouse, has a genome that include a nucleic acid construct having at least one transcriptional regulatory sequence capable of directing expression in B cells of the animal, wherein the transcriptional regulatory sequence is operably linked to a nucleic acid encoding a miR155 gene product. A method of testing the therapeutic efficacy of an agent in treating or preventing a lymphoproliferative condition includes assessing the effect(s) of the agent on a transgenic non-human animal.

Gene expression data provides a basis for more accurate identification and diagnosis of lymphoproliferative disorders. In addition, gene expression data can be used to develop more accurate predictors of survival. The present invention discloses methods for identifying, diagnosing, and predicting survival in a lymphoma or lymphoproliferative disorder on the basis of gene expression patterns. The invention discloses a novel microarray, the Lymph Dx microarray, for obtaining gene expression data from a lymphoma sample. The invention also discloses a variety of methods for utilizing lymphoma gene expression data to determine the identity of a particular lymphoma and to predict survival in a subject diagnosed with a particular lymphoma. This information will be useful in developing the therapeutic approach to be used with a particular subject.

The present invention is related to the branch of immunology and particularly with the generation of pharmaceutical compositions comprising a humanized monoclonal antibody recognizing the leukocyte differentiation antigen CD6. Accordingly with that statement, the purpose of this invention is to provide pharmaceutical compositions comprising a humanized anti-CD6 monoclonal antibody for the diagnosis and treatment of Lymphoproliferative Syndromes and particularly the B-Cell Chronic Lymphocytic Leukemia. The essence of the invention consist in the application of a humanized Monoclonal Antibody that recognizes the CD6 antigen, the generation of pharmaceutical compositions comprising that antibody being able to induce apoptosis of malignant cells from B-Cell Chronic Lymphocytic Leukemia patients, reaching a clinical and a histological antitumor efficacy. The field of application of the present invention extends to the Oncology.

The present invention relates to methods and compositions for the treatment or prevention of diseases and disorder associated with myeloproliferative and lymphoproliferative disorders. In particular, the invention relates to an LSD1 inhibitor for use in treating or preventing diseases and disorder associated with myeloproliferative and lymphoproliferative disorders.

The present invention provides chimeric and humanized versions of anti-CD22 mouse monoclonal antibody, HB22.7. The anti-CD22 antibodies of the invention comprise four human or humanized framework regions of the immunoglobulin heavy chain variable region (“VH”) and four human or humanized framework regions of the immunoglobulin light chain variable region (“VK”). The invention further comprises heavy and / or light chain FW regions that contain one or more backmutations in which a human FW residue is exchanged for the corresponding residue present in the parental mouse heavy or light chain. Human or humanized VH framework regions of antibodies of the invention may comprise one or more of the following residues: a valine (V) at position 24 of framework region 1, a glycine (G) at position 49 of framework region 2, and an asparagine (N) at position 73 of framework region 3, numbered according to Kabat. The invention further relates to pharmaceutical compositions, immunotherapeutic compositions, and methods using therapeutic antibodies that bind to the human CD22 antigen and that preferably mediate human ADCC, CDC, and / or apoptosis for: the treatment of B cell diseases and disorders in human subjects, such as, but not limited to, B cell malignancies, for the treatment and prevention of autoimmune disease, and for the treatment and prevention of graft-versus-host disease (GVHD), humoral rejection, and post-transplantation lymphoproliferative disorder in human transplant recipients.

A novel sphingosine 1-phosphate receptor gene, herein termed sppr, and its splice variants. Sppr is up-regulated in LGL and is useful, for example, in the diagnosis and treatment of certain lymphoproliferative, neurodegenerative and autoimmune diseases.

This current invention provides methods and agents for preventing and treating autoimmune and lymphoproliferative disease by targeting pathogenic age-associated B cells as well as methods of detecting these pathogenic age-associated B cells as a method of diagnosing and predicting autoimmune disease and other lymphoproliferative and chronic inflammatory disorders.The current invention also provides targets for drug development and basic research for autoimmune diseases and other lymphoproliferative and chronic inflammatory disorders.

The present invention relates to novel methods for the diagnosis and therapy of lymphoproliferative diseases. Specifically, the present invention relates to novel methods for the diagnosis and therapy taking advantage of the detection of chromosomal breakpoints in chromosome 12 and / or translocation of chromosomal material from chromosome 12, said chromosomal breakpoints and / or translocation(s) being associated with lymphoproliferative diseases, such as primary cutaneous T-cell lymphomas (CTCL). The present invention further relates to the use of neuron navigator 3 gene (NAV3) or an equivalent or functional fragment thereof involved in chromosomal breakpoints in chromosome 12 and / or translocations thereof, said gene and / or translocations thereof being associated with lymphoproliferative diseases, such as primary cutaneous T-cell lymphomas (CTCL), as a diagnostic and therapeutic agent. The present invention also relates to the development of therapy.
