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.

Novel means useful for definitive diagnosis of a neurological disease accompanied by at least one of inflammation and demyelination, such as multiple sclerosis or neuromyelitis optica, is disclosed. The method for detecting a neurological disease (excluding cerebral infarction) accompanied by at least one of inflammation and demyelination provided by the present invention comprises measuring Crtac1B protein in a sample separated from a subject. The presence of the neurological disease is detected based on a low value of the Crtac1B protein level.

The present invention identifies a compound which binds to the PAH1 domain of mSin3B that specifically binds to neural restrictive silencer factor NRSF, and uses the compound as a prophylactic and/or a therapeutic for diseases associated with abnormal expression of neural restrictive silencer factor NRSF/REST or abnormal expression of genes targeted by NRSF/REST, such as Huntington's disease, medulloblastoma and neuropathic pain. The present invention provides a pharmaceutical composition comprising a substance capable of binding to the PAH1 domain of mSin3B, e.g., a compound represented by the following formula (1), a pharmacologically acceptable salt thereof, or a pharmacologically acceptable ester thereof: wherein n represents 0 or 1; R, R, R, Rand Reach independently represent a hydrogen atom, a hydrocarbon group or a functional group; Y represents a single bond, a carbonyl group, &#x2014;CONH&#x2014;, &#x2014;NHCO&#x2014; or a sulfonyl group; and Z represents a nitrogen-containing heterocyclic group which may have a substituent, an amino group which may have a hydrocarbon group or an aromatic hydrocarbon group, or a nitrogen and oxygen-containing heterocyclic group which may have a substituent.
