Determining Predictors Of Actual Living Kidney Donation Based On Potential Donor Characteristics, Andrea M Meinders, Edward A Graviss, Duc T Nguyen, Jonathan Daw, Krista L Lentine, John Devin Peipert, Ahmed Osama Gaber, David A Axelrod, Francis L Weng, Amy D Waterman

Faculty, Staff and Students Publications

Background: Living donor kidney transplantation is the optimal treatment for end-stage kidney disease; however, few living donor candidates (LDCs) who begin evaluation actually donate. While some LDCs are deemed medically ineligible, others discontinue for potentially modifiable reasons.

Methods: At five transplant centers, we conducted a prospective cohort study measuring LDCs' clinical and psychosocial characteristics, educational preparation, readiness to donate, and social determinants of health. We followed LDCs for 12 months after evaluation to determine whether they donated a kidney, opted to discontinue, had modifiable reasons for discontinuing, were medically ineligible, or had other recipient-related reasons for discontinuing.

Results: Among 2184 …

Immunoregulatory Properties Of Immune Cells That Associate With The Lens Capsule Surface During Acute And Resolution Phases Of Experimental Autoimmune Uveitis, Phuong M. Le, Mary J. Mattapallil, Rachel R. Caspi, Mary Ann Stepp, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Inflammation in the eye is tightly regulated to prevent vision impairment and irreversible blindness. Emerging evidence shows that immune cells are specifically recruited to the lens capsule in response to autoimmune uveitis, yet the potential that they have a role in regulating this inflammatory disease remained unexplored. Here, an immunolocalization approach combined with high-resolution confocal microscopy was used to investigate whether the immune cells that become stably associated with the lens capsule in the eyes of C57BL/6J mice with experimental autoimmune uveitis (EAU) have an immunoregulatory phenotype. These studies revealed that during the acute phase of uveitis, at day 18 …

Absence Of Motor Impairments Or Pathological Changes In Tmem230 Knockout Rats, Wenjuan Zhang, Hao Peng, Daihe Yang, Guohua Song, Juan He, Yun Zhou, Cao Huang, Bo Huang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Parkinson's disease (PD), which is the second most common neurodegenerative disorder, is characterized by progressive movement impairment and loss of midbrain dopaminergic neurons in the substantia nigra. Although mutations in TMEM230 are linked to familial PD, the pathogenic mechanism underlying TMEM230-associated PD remains to be elucidated. To explore the effect of TMEM230 depletion in vivo, we created TMEM230 knockout rats using CRISPR-Cas9 technology. TMEM230 knockout rats did not exhibit any core features of PD, including impaired motor function, loss of dopaminergic neurons in the substantia nigra, or altered expression of proteins related to autophagy, the Rab family, or vesicular trafficking. …

This is of interest to readers to remind them that pancreatic manifestations can occur and are more common in CD.

Challenges Of Insulin-Like Growth Factor-1 Testing, Rongrong Huang, Junyan Shi, Ruhan Wei, Jieli Li

Faculty, Staff and Students Publications

Insulin-like growth factor 1 (IGF-1), primarily synthesized in the liver, was initially discovered due to its capacity to replicate the metabolic effects of insulin. Subsequently, it emerged as a key regulator of the actions of growth hormone (GH), managing critical processes like cell proliferation, differentiation, and apoptosis. Notably, IGF-1 displays a longer half-life compared to GH, making it less susceptible to factors that may affect GH concentrations. Consequently, the measurement of IGF-1 proves to be more specific and sensitive when diagnosing conditions such as acromegaly or GH deficiency. The recognition of the existence of IGFBPs and their potential to interfere …
