Cross-Sectional Survey Of Relevant Literatures As To The Current Proposed Disease Mechanisms And Treatments Of Amyotrophic Lateral Sclerosis (Als), Zachary Sanford Oct 2015

Cross-Sectional Survey Of Relevant Literatures As To The Current Proposed Disease Mechanisms And Treatments Of Amyotrophic Lateral Sclerosis (Als), Zachary Sanford

Marshall Journal of Medicine

Amyotrophic Lateral Sclerosis (ALS), more commonly referred to as Lou Gehrig’s disease, is a progressively degenerative neuromuscular disorder affecting both the upper and lower motor neurons and preferentially affecting males in their forties to seventies. Although the pathology of ALS has been clearly elucidated elsewhere, the precise mechanisms by which the disease progresses and the means by which it is acquired are still poorly understood areas of medicine. Current genomic and proteomic studies in human and animal models have yielded exciting and promising new findings that may help elucidate this pathology. It is the purpose of this review article to …


Selective Involvement Of The Checkpoint Regulator Vista In Suppression Of B-Cell, But Not T-Cell, Responsiveness By Monocytic Myeloid-Derived Suppressor Cells From Mice Infected With An Immunodeficiency-Causing Retrovirus, Kathy A. Green, Li Wang, Randolph J. Noelle, William R. Green Jul 2015

Selective Involvement Of The Checkpoint Regulator Vista In Suppression Of B-Cell, But Not T-Cell, Responsiveness By Monocytic Myeloid-Derived Suppressor Cells From Mice Infected With An Immunodeficiency-Causing Retrovirus, Kathy A. Green, Li Wang, Randolph J. Noelle, William R. Green

Dartmouth Scholarship

Inhibition of T-cell responses in tumor microenvironments by myeloid-derived suppressor cells (MDSCs) is widely accepted. We demonstrated augmentation of monocytic MDSCs whose suppression of not only T-cell, but also B-cell, responsiveness paralleled the immunodeficiency during LP-BM5 retrovirus infection. MDSCs inhibited T cells by inducible nitric oxide synthase (iNOS)/nitric oxide (NO), but uniquely, inhibition of B cells was ~50% dependent each on iNOS/NO and the MDSC-expressed negative-checkpoint regulator VISTA. Blockade with a combination of iNOS/NO and VISTA caused additive or synergistic abrogation of MDSC-mediated suppression of B-cell responsiveness.


Novel Advances In Alzheimer's Disease, Jacob P. Naumann May 2015

Novel Advances In Alzheimer's Disease, Jacob P. Naumann

The Downtown Review

Alzheimer’s disease, the most common form of dementia in adults, is a progressive degenerative neurological disease that affects memory, cognition, and behavior. Dr. Alois Alzheimer discovered and diagnosed the irreversible disease in 1906 after documenting the famous case of Auguste Deter.1 Since the discovery of the disease, numerous advances have made it possible to not only better understand the causal factors, but also to improve the medical diagnosis and preventative measures that healthcare providers can implement. For the first time since 1984, the National Institute on Aging (NIAA) and the Alzheimer’s Association (AA) proposed and published new diagnostic guideline …


Cohort Of Birth Modifies The Association Between Fto Genotype And Bmi, James Niels Rosenquist, Steven F. Lehrer, A. James O'Malley, Alan M. Zaslavsky, Jordan W. Smoller, Nicholas A. Christakis Jan 2015

A substantial body of research has explored the relative roles of genetic and environmental factors on phenotype expression in humans. Recent research has also sought to identify gene-environment (or g-by-e) interactions, with mixed success. One potential reason for these mixed results may relate to the fact that genetic effects might be modified by changes in the environment over time. For example, the noted rise of obesity in the United States in the latter part of the 20th century might reflect an interaction between genetic variation and changing environmental conditions that together affect the penetrance of genetic influences. To evaluate this …
