Neuropathological Examination

ABSTRACT The occurrence of dementia in amyotrophic lateral sclerosis (ALS) was only widely recognized in the late 20th century. Hitherto, it was believed that dementia was a rare event due to the fortuitous association with other diseases. In 1924, Kostantin Nikolaevich Tretiakoff and Moacyr de Freitas Amorim reported a case of dementia with features of frontotemporal dementia (FTD) that preceded the motor signs of ALS. Neuropathological examination confirmed ALS and found no signs of other dementia-causing diseases. The authors hypothesized that dementia was part of ALS and recommended the search for signs of involvement of motor neurons in cases of dementia with an ill-defined clinical picture, a practice currently accepted in the investigation of cases of FTD. This was one of the first descriptions of dementia preceding the motor impairments of ALS and was published in Portuguese and French in Memórias do Hospício de Juquery.

Inflammation is a shared hallmark between amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). For long, studies were conducted on tissues of post-mortem patients and neuroinflammation was thought to be only bystander result of the disease with the immune system reacting to dying neurons. In the last two decades, thanks to improving technologies, the identification of causal genes and the development of new tools and models, the involvement of inflammation has emerged as a potential driver of the diseases and evolved as a new area of intense research. In this review, we present the current knowledge about neuroinflammation in ALS, ALS-FTD, and FTD patients and animal models and we discuss reasons of failures linked to therapeutic trials with immunomodulator drugs. Then we present the induced pluripotent stem cell (iPSC) technology and its interest as a new tool to have a better immunopathological comprehension of both diseases in a human context. The iPSC technology giving the unique opportunity to study cells across differentiation and maturation times, brings the hope to shed light on the different mechanisms linking neurodegeneration and activation of the immune system. Protocols available to differentiate iPSC into different immune cell types are presented. Finally, we discuss the interest in studying monocultures of iPS-derived immune cells, co-cultures with neurons and 3D cultures with different cell types, as more integrated cellular approaches. The hope is that the future work with human iPS-derived cells helps not only to identify disease-specific defects in the different cell types but also to decipher the synergistic effects between neurons and immune cells. These new cellular tools could help to find new therapeutic approaches for all patients with ALS, ALS-FTD, and FTD.
