Cannabinoid receptor CB2 modulates axon guidance.

Navigation of retinal projections towards their targets is regulated by guidance molecules and growth cone transduction mechanisms. Here, we present in vitro and in vivo evidences that the cannabinoid receptor 2 (CB2R) is expressed along the retino-thalamic pathway and exerts a modulatory action on axon guidance. These effects are specific to CB2R since no changes were observed in mice where the gene coding for this receptor was altered (cnr2 (-/-)).

Concerted action of CB1 cannabinoid receptor and deleted in colorectal cancer in axon guidance.

Endocannabinoids (eCBs) are retrograde neurotransmitters that modulate the function of many types of synapses. The presence of eCBs, their CB1 receptor (CB1R), and metabolizing enzymes at embryonic and early postnatal periods have been linked to developmental processes such as neuronal proliferation, differentiation, and migration, axon guidance, and synaptogenesis. Here, we demonstrate the presence of a functional eCB system in the developing visual system and the role of CB1R during axon growth and retinothalamic development.

The Effect of Imatinib Mesylate for Newly Diagnosed Philadelphia Chromosome-Positive, Chronic-Phase Myeloid Leukemia in Sub-Saharan African Patients: The Experience of Côte d'Ivoire.

Imatinib mesylate, showed encouraging activity in chronic myelogenous leukemia. However, there are few data regarding his efficacy and response monitoring in Sub-Saharan African patients. Our objective was to assess response to imatinib mesylate (Glivec) in Côte d'Ivoire patients with newly diagnosed Chronic Myeloid Leukemia (CML).

Results of treatment with CMA, a low intermediate regimen, in endemic Burkitt lymphomas in sub-Saharian Africa: experience of Côte d'Ivoire.

African Burkitt lymphomas (BL) are highly aggressive lymphomas mainly affecting children and young adults in Africa. This lymphoma was marked by its high sensitivity to chemotherapy in comparison to Sporadic Burkitt lymphoma. In this study, we evaluated the treatment response and survival of patients with CMA protocol.

[Chronic lymphoid leukemia in the Ivory Coast. (69 cases)].

We report on sixty-nine cases of chronic lymphocytic leukaemia. This report describes the result over a period of eleven years. We have pointed out that chronic lymphocytic leukaemia is most frequent in adults.

[Adult T-cell leukemia associated with HTLV1 and positive HIV2 serology in an African woman].

We report a case of acute adult T-cell leukemia associated with HTLV1 infection in a young African woman. The leukemic proliferation consisted of CD4-, CD25-positive lymphoid cells with typically convoluted nuclei and monoclonal integration of the HTLV1-proviral DNA. The clinical course was characterized by a rapid progression of the leukemia with development of hypercalcemia, resistance to chemotherapy, and the presence of multiple opportunistic infections.

Chemotherapy-radiotherapy versus chemotherapy in Hodgkin's disease with bone marrow involvement. Retrospective analysis of 32 cases.

A retrospective analysis was performed on 32 patients suffering from Hodgkin's disease with bone marrow involvement treated between 1972 and 1976. After 6 courses of chemotherapy (MOPP for 25 patients), we observed 20 complete remissions (62.5%), 8 lymph node partial remissions (bone marrow sterilization but persistence of pathological lymph nodes) and 4 failures.
