Placental CpG Methylation on HPA Axis Genes Caused by Conflict-Zone Stress

July 3, 2020 Catherine Mancilla
Catherine Mancilla Introduction. When pregnant people experience stress, the glucocorticoids they produce to manage their own stress response cross the placenta and enact epigenetic changes on fetal neurodevelopment.1-4 These epigenetic changes include CpG methylation and are prominent in the hypothalamic-pituitary-adrenocortical (HPA) axis,1-4 leading to altered responses to stress throughout the…

The role of short chain fatty acids in alleviating anxiety by reducing gut corticotropin releasing factor receptor (CRFR) expression and systemic inflammation

July 2, 2020 Lena Ayari
Lena Ayari Introduction. Generalized anxiety disorder (GAD) is one of the top causes of mental illness in the U.S., affecting around 3.1% of the population.1 Current pharmaceutical therapies are associated with unpleasant and potentially harmful side effects, and only around 45-55% of those affected achieve remission following treatment.1,2 Studies have…

Mesenchymal Stem Cell-Mediated Survival of Pancreatic Beta Cells Via the Induction of Cellular Signaling Pathways: Akt and Wnt4-Beta-Catenin

July 31, 2019 Kirby James Taylor
Kirby James Taylor Introduction. Type 1 diabetes mellitus (T1D) is a heterogeneous disorder effecting 1 and 300 Americans characterized by the destruction of pancreatic beta cells, resulting in an insulin deficiency [1]. Beta cells with immune infiltration from CD4+ T cells express specific HLA class II proteins, that cause T-cell…

Diabetic Wound Healing: New Targets and Approaches

July 16, 2019 Pouriska Kivanany
Pouriska Kivanany Introduction. Diabetes is characterized by elevated blood glucose levels, decreased blood circulation, and reduced immune response.1, 2 Diabetic foot ulcers are the primary complication with diabetes and are responsible for 84% of diabetic lower leg amputations.3 In normal wound healing, there is an interplay between cells, extracellular matrix, and biochemical/biophysical…

Extracellular vesicles derived from mesenchymal stem cells attenuate the immune response in Type 1 Diabetes by inducing regulatory dendritic cells

July 1, 2019 Ather Adnan
Ather Adnan Introduction: Type 1 Diabetes (T1D) is a complex autoimmune disease characterized by T-cell driven destruction of pancreatic β-cells in the islets of Langerhans and resultant hyperglycemia1. The pathogenesis of T1D involves presentation of normally cryptic β-cell autoantigens and aberrant activation rather than suppression of immune cells1,2. The only…

The Role of Oxytocin in Relation to the HPA axis and Differential Receptor Methylation Patterns in the Prognosis and Prevention of Postpartum Depression

July 25, 2018 Allyson Jones
Allyson Jones Introduction: Postpartum depression, which effects as many as 30% of mothers, impairs mother-infant interactions and can have a profound effect on both child development and motherhood.1 Oxytocin is a key regulatory hormone that is known to buffer stress reactivity, support positive mood, and promote healthy mothering behaviors.2 While…
