[Aluminum-induced osteopathy--pathogenetic mechanisms].

Area of Science:

• Biochemistry
• Toxicology
• Bone Biology

Context:

• Aluminum accumulation in the body is a known factor contributing to bone metabolism disruption.
• While the causal link is established, the exact pathomechanisms of aluminum toxicity on bone remain debated.
• Extraosseous factors modulating bone turnover are influenced by the body's aluminum load.

Purpose:

• To explore the complex pathogenetic principles underlying aluminum-induced bone changes.
• To elucidate the specific mechanisms by which aluminum affects bone metabolism.
• To review the current understanding of aluminum's impact on mineralization, bone cells, and related factors.

Summary:

• Aluminum accumulation is causally linked to toxic effects on bone metabolism.
• Key pathomechanisms discussed include inhibition of mineralization, direct toxicity to bone cells, interactions with nicotinamide adenine dinucleotide (NAD+) function, and effects on vitamin D balance.
• The precise molecular and cellular pathways mediating aluminum's detrimental effects on bone require further clarification.

Impact:

• Provides a comprehensive overview of the current knowledge on aluminum-induced bone disease.
• Highlights areas of ongoing research and debate in the field.
• Informs future research directions for understanding and potentially mitigating aluminum toxicity in bone.
