Zyclara (imiquimod)

RrcHSIL non-responders to imiquimod exhibited an even more immunosuppressive microenvironment than complete responders, characterized by increased infiltration of CD4 + FoxP3 + regulatory T cells and (CD14 + )CD68 + CD163 + M2-like macrophages and CD14 + HLADR- monocytic myeloid derived suppressor cells. The limited efficacy of imiquimod in rrcHSIL may be explained by a strong immunosuppressive microenvironment.

DHU-OH-6 enables fluorescence imaging of exogenous and endogenous HOCl in cells and provides fluorescence-guided therapy in an imiquimod-induced psoriasis mouse model, where it alleviates psoriatic skin lesions and mitigates systemic toxicity relative to free CPT. This HOCl-activated hydroxyl drug-release platform offers a generalizable strategy for the design of site-selective, image-guided prodrugs for HOCl-overexpressing diseases.

Mice were divided into five groups: control (cream base), imiquimod (IMQU; 62.5 mg/day for 7 days), a commonly used inducer of psoriasis-like dermatitis, standard (tacrolimus 20 mg/kg/day, 2 h after IMQU), IMQU + D...These findings suggest that D. tortuosa and D. triradiata NCs possess promising anti-psoriatic potential, through immunomodulatory and anti-inflammatory mechanisms, with D. tortuosa demonstrating superior efficacy. They may serve as effective natural alternatives to conventional psoriasis treatments.

Here, we determined and compared the efficacy of sodium R-lipoate (NaRLA, 50 and 100 mg/kg body weight/day), given orally for 8 consecutive days, in a BALB/c mouse model of imiquimod-induced psoriatic skin inflammation, in comparison with the synthetic drug methotrexate (MTX). Furthermore, NaRLA resulted in a significant improvement (P < 0.001) on both Evans blue extravasation and mast cell degranulation, suggesting a reduction in inflammation and edema. Thus, our observations imply that NaRLA may serve as an effective agent for alleviating psoriatic skin inflammation via targeting IL-23/IL-17A axis and mast cell degranulation.

In a rat collagen-induced arthritis model, anti-TL1A antibody treatment effectively reduced arthritis severity, with similar efficacy to the TNF antagonist etanercept. In humanized mouse Imiquimod-induced psoriasis and 2,4,6‑trinitrobenzene sulfonic acid colitis models, anti-TL1A demonstrated similar efficacy to anti-IL-23 and anti-TNF antibodies. These findings characterize two novel extended half-life TL1A antibodies and support the ongoing Phase 2 clinical development of SPY002 and SPY072 for immune-mediated diseases such as inflammatory bowel disease and rheumatic diseases.

Results showed that Khib modification levels at the K42 site of ACTR3 were significantly reduced in lesional tissues from psoriatic patients and imiquimod (IMQ)-induced psoriatic mice...Notably, TAK1 antagonists effectively reversed abnormal keratinocyte proliferation and psoriatic inflammation induced by the ACTR3 K42A mutation. This study elucidates that reduced Khib modification at the ACTR3 K42 locus promotes keratinocyte proliferation via regulation of the TAK1-MK2-HSP27 signalling pathway, offering a previously undescribed molecular insight into psoriasis pathogenesis.

TLR3 and TLR7 agonists induce IFN-driven monocyte activation in PWH, which is effectively modulated by JAK-STAT inhibitors. These findings support their potential as therapeutic agents to mitigate inflammation in chronic HIV infection.

Under acidic conditions, it undergoes structural disassociation, leading to the release of therapeutic components of a near-infrared photosensitizer (FBC) and the Toll-like receptor 7 (TLR7) agonist imiquimod (IMQ)...In vivo experiments demonstrated that FI@PMD increased the infiltration of CD8+ cytotoxic T cells in tumor tissues to 2.85-fold of that in the PBS group while reducing the proportion of Treg cells to 0.86-fold. Collectively, this TAM-targeted reprogramming strategy provides a promising approach to overcome immunosuppressive TME and enhance the efficacy of photodynamic immunotherapy in malignant tumors.

Activation of skin local sympathetic signaling in KCs induces CXCL1 production via the ADRB2-CREB pathway, which contributes to recruiting neutrophils to the skin lesions and fuels psoriatic inflammation.
