β-Methylamino-L-alanine, or BMAA, is a non-proteinogenic amino acid produced by cyanobacteria. BMAA is a neurotoxin. Its potential role in various neurodegenerative disorders is the subject of scientific research.

In the present review we have discussed the occurrence of β-N-methylamino-L-alanine (BMAA) and its natural isomers, and the organisms and sample types in which the toxin(s) have been detected. Further, the review discusses general pathogenic ...

2017年2月21日 · BMAA is considered a strong contender as the cause of, or at least a major contributor to, both endemic and sporadic ALS and Alzheimer’s disease, and possibly conferring risk for Parkinson’s diseases as well.

The Baptist Missionary Association of America (BMAA) is a fellowship of Independent Baptist churches. Historically, churches within the BMAA have generally been associated with theological conservatism and the Landmarkism movement.

The compound BMAA (β-N-methylamino-L-alanine) has been postulated to play a significant role in four serious neurological human diseases: Amyotrophic Lateral Sclerosis/Parkinsonism Dementia Complex (ALS/PDC) found on Guam, and ALS, Parkinsonism, and ...

2018年12月20日 · BMAA is a candidate environmental risk factor for neurodegenerative diseases such as amyotrophic lateral sclerosis and Parkinson-dementia complex.

2009年8月7日 · BMAA is considered a possible cause of the amyotrophic lateral sclerosis/parkinsonism-dementia complex (ALS/PDC). Its neurotoxic effects may include degenerative locomotor diseases resulting from damage to cells (such as neurons) in the motor cortex and spinal cord.

2021年10月5日 · The remaining proposed mechanisms of BMAA toxicity have received less attention. BMAA is a strong chelator of metal ions such as Cu 2+, Zn 2+, and Ni 2+ that are important for normal neurotransmission and cellular functions in the CNS (Nunn et al. 1987). For example, zinc-dependent transcription factors are essential for the transcription of ...
