Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelObservational studyMechanism

    In brain tissue of environmentally lead-exposed humans, reversed-phase HPLC of the lead-binding protein fraction isolated thymosin beta‑4 (5 kDa) as one of two proteins.

    In plain wordsIn brain tissue from people exposed to lead, the body's own thymosin beta‑4 was one of two proteins isolated from the lead-binding fraction.

    Summary · context
    This study reports the partial purification and characterization of cytosolic lead binding proteins (PbBPs) in human brain tissue of environmentally Pb-exposed subjects.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyMechanism

    In brain tissue of environmentally lead-exposed humans, qualitative 203Pb-binding analysis suggested that the two HPLC-purified proteins, including thymosin beta‑4, may be primarily responsible for the observed lead binding.

    In plain wordsIn brain tissue from people exposed to lead, two purified proteins, one being the body's own thymosin beta‑4, may be mainly responsible for lead binding.

    Summary
    Qualitative 203Pb-binding analysis of these HPLC purified proteins suggested that they may be primarily responsible for the observed Pb binding in the single DEAE peak.
