Proinflammatory agonists provoke the expression of cell surface adhesion molecules on endothelium in order to facilitate leukocyte infiltration into tissues. Rigorous control over this process is important to prevent unwanted inflammation and organ damage. Protein L-isoaspartyl O-methyltransferase (PIMT) converts isoaspartyl residues to conventional methylated forms in cells undergoing stress-induced protein damage. The purpose of this study was to determine the role of PIMT in vascular homeostasis. PIMT is abundantly expressed in mouse lung endothelium and PIMT deficiency in mice exacerbated pulmonary inflammation and vascular leakage to LPS(lipopolysaccharide). Furthermore, we found that PIMT inhibited LPS-induced toll-like receptor signaling through its interaction …

Treatment failure in joint infections is associated with fibrinous, antibiotic-resistant, floating and tissue-associated Staphylococcus aureus aggregates formed in synovial fluid (SynF). We explore whether antibiotic activity could be increased against Staphylococcus aureus aggregates using ultrasound-triggered microbubble destruction (UTMD), in vitro and in a porcine model of septic arthritis. In vitro, when bacterially laden SynF is diluted, akin to the dilution achieved clinically with lavage and local injection of antibiotics, amikacin and ultrasound application result in increased bacterial metabolism, aggregate permeabilization, and a 4-5 log decrease in colony forming units, independent of microbubble destruction. Without SynF dilution, amikacin + UTMD does …

Lysosomal inhibition elicited by palmitoyl-protein thioesterase 1 (PPT1) inhibitors such as DC661 can produce cell death, but the mechanism for this is not completely understood. Programmed cell death pathways (autophagy, apoptosis, necroptosis, ferroptosis, and pyroptosis) were not required to achieve the cytotoxic effect of DC661. Inhibition of cathepsins, or iron or calcium chelation, did not rescue DC661-induced cytotoxicity. PPT1 inhibition induced lysosomal lipid peroxidation (LLP), which led to lysosomal membrane permeabilization and cell death that could be reversed by the antioxidant N-acetylcysteine (NAC) but not by other lipid peroxidation antioxidants. The lysosomal cysteine transporter MFSD12 was required for intralysosomal transport …

Review Of Surgical Management For Closed-Angle Glaucoma, Scott Kozarsky, Ba

inSIGHT

Closed-angle glaucoma, also known as angle-closure glaucoma, is one of the major types of glaucoma. Glaucoma is a term used to describe a broad group of ocular diseases that damage the optic nerve. The type of angle closure with which the patient presents, whether acute, subacute, or chronic, will dictate their treatment. Management of these three presentations will be discussed at length later in this article. In the United States, closed-angle glaucoma is less common than open-angle glaucoma, which often has a gradual onset of intraocular pressure (IOP) elevation and optic nerve damage.

Age-Related Macular Degeneration And Emerging Treatments – With Advice From Dr. Ajay Kuriyan On Balancing Research With Clinical Responsibilities, Charles Deyoung, Ba

inSIGHT

Age-related macular degeneration (AMD) is a chronic disease of the central retina and a leading cause of vision loss worldwide. Although the early stages of AMD may present asymptomatically, the disease may progress and lead to severe visual impairment via geographic atrophy (“late dry”) or neovascular (“wet”) AMD. In geographic atrophy (GA), there is progressive atrophy of the retinal pigment epithelium (RPE), choriocapillaris, and photoreceptors due to lipofuscin (Drusen) accumulation between the RPE and Bruch’s membrane.¹ These Drusen deposits grow and create an inflammatory and metabolically dysfunctional environment for the photoreceptors supplying the macula (Figure 1).² Eventually, the …

A Look Into Oculoplastics: Repairing Lower Eyelid Defects From Carcinomas, Cameron Haghshenas, Bs

inSIGHT

Eyelids are the thinnest, most sensitive skin we have and can easily be damaged by sun exposure. This is evident given that 5 - 10% of all skin cancers occur on the eyelid, and over half of these occur on the lower eyelid¹. Most of such cases are basal cell carcinomas, which are slow-growing cancers that arise from the basal cell layer, the deepest part of the epidermis. If left untreated or improperly treated, these tumors can extend into adjacent tissues and bone, or recur. Squamous cell carcinomas can also occur on the lower eyelid, although they represent …

Mechanisms Of Chromosomal Instability (Cin) Tolerance In Aggressive Tumors: Surviving The Genomic Chaos, Brittiny Dhital, Veronica Rodriguez-Bravo

Student Papers, Posters & Projects

Chromosomal instability (CIN) is a pervasive feature of human cancers involved in tumor initiation and progression and which is found elevated in metastatic stages. CIN can provide survival and adaptation advantages to human cancers. However, too much of a good thing may come at a high cost for tumor cells as excessive degree of CIN-induced chromosomal aberrations can be detrimental for cancer cell survival and proliferation. Thus, aggressive tumors adapt to cope with ongoing CIN and most likely develop unique susceptibilities that can be their Achilles' heel. Determining the differences between the tumor-promoting and tumor-suppressing effects of CIN at the …
