Antagonists of leukotriene D4 (LTD4), 3-[7-(2-n-propyl-3-hydroxy-4-acetyl- phenoxy)-propoxy-2-methyl-3,4-dihydro-4-8-n-propyl-2H-1-benzopyran- 2-yl]-propionic acid (SC-39070) and 7-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)-2-hydroxy- propoxy]-4-methyl- 2-oxo-2H-1-benzopyran-3-acetic acid (FPL-60319) were locally administered to eyes of rabbits with immunogenic keratitis. The period of circular leukocyte infiltration (Wessely's ring) in the cornea was markedly decreased. Edema and neovascularization of the cornea were not influenced.

Trastuzumab-Induced Early Corneal Melt in HER2-Positive Breast Cancer: A Case Report and Review.

BACKGROUND Trastuzumab (Herceptin) is a recombinant DNA-derived humanized monoclonal antibody that the US Food and Drug Administration (FDA) approved in 1998 for metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer therapy. It selectively binds to the extracellular domain of HER2 and mediates an antibody-dependent cellular toxicity in various tissues. Trastuzumab use alone does not typically cause aggressive ocular complications.

Article Synopsis
- Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
- Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
- Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.

CD80 is the best-known costimulatory molecule for effective T cell functions. Many different reports have summarized the role of CD80 in HSV-1 and its functions in maintaining adaptive immunity, which is the main player in causing herpes stromal keratitis (HSK). To determine the effects of absence or overexpression of CD80 in HSV-1 infection, we infected CD80 and WT mice with a recombinant HSV-1 expressing murine CD80 (HSV-CD80) in place of the latency associated transcript (LAT).

Article Synopsis
- * This study tested sodium butyrate (NaB), which can reduce pro-inflammatory cytokines and promote anti-inflammatory ones, to see if it could improve keratitis treatment.
- * Results showed that NaB did not harm corneal fibroblast viability, helped maintain a healthy cell type, inhibited cell movement, and reduced inflammation by targeting the JAK/STAT signaling pathway.

Article Synopsis
- * A specific bacteria, which is common in the eye, decreases in abundance as we age and can behave as both an infectious agent and an immune trigger.
- * The review focuses on how this bacteria contributes to various eye inflammations, affecting diagnosis and treatment strategies.
