Potential Diagnosis of Vitreoretinal Lymphoma by Detection of MYD88 Mutation in Aqueous Humor With Ultrasensitive Droplet Digital Polymerase Chain Reaction.
Myocilin protein was detected in all control AH samples but was nearly undetectable in AH samples from a patient heterozygous for the Val251Ala mutation.
In addition, a nonsense RB1 mutation (Lys→STOP) from 1 child was also identified from the AH samples obtained during intravitreous injection of melphalan, which matched the tumor sample postsecondary enucleation.
While the underlying cause of POAG remains unclear, TGF-β2-dependent remodeling of the extracellular matrix (ECM) within the trabecular meshwork (TM) microenvironment is considered an early pathologic consequence associated with impaired aqueous humor (AH) outflow and elevated IOP.
Transforming growth factor β2 (TGFβ2) is elevated in the AH and TM of primary open angle glaucoma (POAG) patients and induces POAG-associated TM changes, including CLANs.
The levels of the cytokines (interleukin [IL]-4, IL-6, IL-8, IL-10, IL-12p70, IL-17A, interferon [IFN]-γ, monocyte chemotactic protein [MCP]-1, E-selectin, P-selectin, and soluble intercellular adhesion molecule [sICAM]-1) in the AqH were measured with multiplex beads immunoassay.
This system is applied to assess the angiogenic capacity of aqueous humor (AH) from patients with ocular disorders, and to test the effect of VEGF inhibitor (aflibercept) on induced angiogenesis.
Using bead-based immunoassay analysis we were able to detect a significantly higher concentration of the B cell-activating and survival factors BAFF, APRIL, and IL-6 in the AqH of JIAU and AAU patients than in POAG patients.
Even though visual acuity response and anatomic effect are not always correlated in DME, we found that baseline elevated MCP-1AH levels and DRT pattern were biomarkers that predicted a future favorable anatomic response to DEX.
From anterior chamber of rabbit eye aqueous humor was collected to assess various oxidative stress parameters like malondialdehyde, superoxide dismutase, glutathione peroxidase, catalase, nitric oxide, and inflammatory parameters like TNF-<i>α</i> and IL-6.
One hundred nineteen patients for whom IL-10 and IL-6 in the AH and/or vitreous had been measured were included: 16 patients with a final diagnosis of VRL and 103 patients with final diagnosis of uveitis.
Relapsed DME cases (T3) showed significantly higher levels of IL-6 (<i>p</i> = .028), IL-8 (<i>p</i> = .005), IP-10 (<i>p</i> = .013) and MCP-1 (<i>p</i> = .005) compared to T2.<i>Conclusion</i>: IP-10 and MCP-1AH levels seem to be related to DEX intraocular action, decreasing after injection and increasing when DME relapses.
To determine concentrations of endoplasmic reticulum (ER) stress-related factors activating transcription factor 4 (ATF4) and glucose-regulated 78 kDa protein (GRP78) in vitreous and aqueous humor (AqH) of patients with proliferative diabetic retinopathy (PDR) and the correlation of ATF4, GRP78 and inflammatory cytokines interleukin-6(IL-6) and monocyte chemoattractant protein-1 (MCP-1).
To identify disease-specific cytokine profile differences in the aqueous humor (AH) (other than the vascular endothelial growth factor) between patients with dry and treated wet age-related macular degeneration (AMD) and healthy controls.
The levels of cytokines (interleukins [ILs]-1α, -1β, -4, -6, -8, -10, -12p70, -13, -17A, interferon [IFN]-α, IFN-γ, monocyte chemotactic protein [MCP]-1, E-selectin, P-selectin, and soluble intercellular adhesion molecule-1 [sICAM-1]) in the AqH were measured using multiplex beads immunoassay.
We assayed aqueous humor (AH) samples from patients with Behçet's disease (BD), Vogt-Koyanagi-Harada (VKH) disease, and HLA-B27-associated uveitis and control patients for the proinflammatory cytokines IL-15, IL-17, interferon-γ and tumor necrosis factor-α and the immunosuppressive cytokine IL-10.
The mean concentrations of IL-6, MCP-1 were also higher in both AqH and vitreous samples from patients with PDR compared to those of IMH (all p < 0.001).
The levels of cytokines (interleukin [IL]-1α, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-17A, interferon [IFN]-α, IFN-γ, monocyte chemotactic protein [MCP]-1, E-selectin and P-selectin) in AqH were measured by multiplex bead immunoassay.
Reverse-transcription polymerase chain reactions, IHC staining, Western blot analysis, and ELISA showed that cilostazol inhibited mRNA and protein expressions of intercellular adhesion molecule-1, monocyte chemoattractant protein-1 and fractalkine in the retina and aqueous humor (AqH).
