Case Western Reserve University researchers have identified a mechanism in brain tissue that may explain why women are more vulnerable to Alzheimer’s disease—a finding that they say could help lead to new medicines to treat the disease. The researchers found that the female brain shows higher expression of a certain enzyme compared to males, resulting in greater accumulation of a protein called tau.
Scientists at the Icahn School of Medicine at Mount Sinai saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals—muskoxen and bighorn sheep. The results published in the journal Acta Neuropathologica may contradict the commonly-held belief that ramming animals do not suffer brain injuries and support the notion that studies on animals with brains evolutionarily similar to those of humans may help researchers understand and reduce traumatic brain injuries.
A study suggests that reducing tau protein in brain neurons will not protect against Parkinson’s disease and Lewy body dementias. If borne out, this result differs from Alzheimer’s disease, where reducing endogenous tau levels in brain neurons is protective for multiple models of the disease.
A team of researchers at the Case Western Reserve University School of Medicine has taken a major step toward understanding the mechanisms involved in the formation of large clumps of tau protein, a hallmark of Alzheimer’s disease and several other neurodegenerative disorders.
