The present invention mainly addresses the problem of providing an antibody against semaphorin 3A protein, said antibody enabling effective prevention and/or treatment of a disease, in which Sema 3A protein participates, such as a neurodegenerative disease, autoimmune disease, inflammatory disease, cancer, infectious disease, etc. or disseminated intravascular coagulation syndrome. An anti-Sema 3A antibody comprising CDRs having specific amino acid sequences (SEQ ID NOS: 1-6, 60-62, 64-66, 68-70, 72-74, 76-78, 80-82, 84-86 and 88-90) enables effective prevention and/or treatment of a disease, in which Sema 3A protein participates, such as a neurodegenerative disease, autoimmune disease, inflammatory disease, cancer, infectious disease, etc. or disseminated intravascular coagulation syndrome and, therefore, remarkably ameliorates symptoms associated with such a disease.

The present invention relates to neurological and physiological dysfunction associated with neuron disorders. In (particular, the invention relates to the involvement of vascular endothelial growth factor (VEGF) and homologues in the aetiology of motor neuron disorders. The invention further concerns a novel, mutant transgenic mouse (VEGFm/m) with a homozygous deletion in the hypoxia responsive element (HRE) of the VEGF promoter which alters the hypoxic upregulation of VEGF. These mice suffer severe adult onset muscle weakness due to progressive spinal motor neuron degeneration which is reminiscent of amyotrophic lateral sclerosis (ALS)-a fatal disorder with unknown aetiology. Furthermore, the neuropathy of these mice is not caused by vascular defects, but is due to defective VEGF-mediated survival signals to motor neurons. The present invention relates in particular to the isoform VEGF165 which stimulates survival of motor neurons via binding to neuropilin-1, a receptor known to bind semaphorin-3A which is implicated in axon retraction and neuronal death, and the VEGF Receptor-2. The present invention thus relates to the usage of VEGF, in particular VEGF165, for the treatment of neuron disorders and relates, in addition, to the usage of polymorphisms in the VEGF promotor for diagnosing the latter disorders.
