BACKGROUND: Melanoma in situ (MIS) is a noninvasive form of melanoma for which nonsurgical therapeutic options continue to be explored. The off-label use of topical 5% imiquimod cream in the management of MIS has shown potential but reported recurrence rates vary considerably between 0% and 40%. Furthermore, the long-term efficacy of imiquimod is not well established. OBJECTIVE: To determine the recurrence rate of MIS among patients treated with topical 5% imiquimod cream at Dartmouth-Hitchcock Medical Center with at least 1 year of follow-up...

BACKGROUND: Prophylactic vaccines are available for women and girls not yet infected with HPV, but women already infected with HPV need a treatment to prevent progression to high-grade cervical lesions and cancer. GTL001 is a bivalent therapeutic vaccine for eradicating HPV-infected cells that contains HPV16 E7 and HPV18 E7 both fused to detoxified adenylate cyclase from Bordetella pertussis, which binds specifically to CD11b+ antigen-presenting cells. This study examined the ability of therapeutic vaccination with GTL001 adjuvanted with topical imiquimod cream to induce functional HPV16 E7- and HPV18 E7-specific CD8+ T cell responses...

The role of viral infections in adverse pregnancy outcomes has gained interest in recent years. Innate immune pattern recognition receptors (PRRs) and their signalling pathways that yield a cytokine output in response to pathogenic stimuli have been postulated to link infection at the maternal-fetal interface and adverse pregnancy outcomes. The objective of this study was to investigate the expression and functional response of nucleic acid ligand responsive Toll-like receptors (TLR3, 7, 8 and 9), and retinoic acid-inducible gene 1 (RIG-I)-like receptors (RIG-I, MDA5 and LGP2) in human term gestation-associated tissues (placenta, choriodecidua and amnion) using an explant model...

BACKGROUND: Porokeratosis (PK) is a rare skin disease of unknown etiology. It consists of a keratinization disorder, which may appear in several clinical forms and can undergo malignant transformation. The histopathological hallmark of PK is the cornoid lamella. While many topical, systemic, and surgical treatment modalities for PK have been described, no randomized controlled trials have been performed yet. Because of a lack of treatment standards for PK, European and international guidelines cannot be created...

BACKGROUND: Imiquimod (IMQ) produces a cutaneous phenotype in mice frequently studied as an acute model of human psoriasis. Whether this phenotype depends on strain or sex has never been systematically investigated on a large scale. Such effects, however, could lead to conflicts among studies, while further impacting study outcomes and efforts to translate research findings. METHODS: RNA-seq was used to evaluate the psoriasiform phenotype elicited by 6 days of Aldara (5% IMQ) treatment in both sexes of seven mouse strains (C57BL/6 J (B6), BALB/cJ, CD1, DBA/1 J, FVB/NJ, 129X1/SvJ, and MOLF/EiJ)...

Psoriasis is a chronic inflammatory skin disease characterized by abnormal keratinocyte proliferation and terminal differentiation. Interleukin-22 (IL-22) and the transcription factor Stat3 play pivotal roles in the pathogenesis of psoriasis. CD147 is a transmembrane glycosylation protein that belongs to the immunoglobulin superfamily. Our previous studies have shown that CD147 is a marker of high keratinocyte proliferation and poor keratinocyte differentiation as well as a psoriasis susceptibility gene. The current study demonstrates that CD147 is highly expressed in psoriatic skin lesions...

In chronic diseases, such as HIV infection, plasmacytoid dendritic cells (pDCs) are rendered dysfunctional, as measured by their decreased capacity to produce IFN-α. In this study, we identified elevated levels of T cell Ig and mucin-domain containing molecule-3 (Tim-3)-expressing pDCs in the blood of HIV-infected donors. The frequency of Tim-3-expressing pDCs correlated inversely with CD4 T cell counts and positively with HIV viral loads. A lower frequency of pDCs expressing Tim-3 produced IFN-α or TNF-α in response to the TLR7 agonists imiquimod and Sendai virus and to the TLR9 agonist CpG...

Actinic keratoses (AKs) are intraepithelial atypical proliferations of keratinocytes that develop in skin that has undergone long-term exposure to ultraviolet radiation. Given the ageing population and an increasing prevalence of AK, the socio-economic burden of AK is likely to rise over the coming years. Areas of subclinical (non-visible) sun damage in the periphery of visible AK lesions contain the same genetic changes as those found in the lesions themselves, and are known as areas of field cancerization...

Herpes Simplex Virus type 2 is the primary cause of genital ulceration worldwide. The presence of atypical features like deep ulcerations, hypertrophic, or pseudotumoural lesions or unusual location can be a marker for co-infection with HIV. These immunocompromised patients are usually resistant to the conventional antiviral treatment. We present a case of an HIV-infected patient with hypertrophic herpes genitalis, refractory to conventional oral antiviral therapy, who was successfully treated with a combination of oral valcyclovir and topical application of 5% imiquimod...

The hybrid system based on nanoparticles (NPs) self-assembled by the conjugations of hyaluronic acid with cholesterol (HA-Chol NPs) combined with nicotinamide (NIC) for tacrolimus (FK506), ie, FK506 NPs-NIC, has been confirmed to exhibit a significant synergistic effect on FK506 permeation through and into intact skin; thus, it may be a promising approach for FK506 to effectively treat skin diseases. The aim of this study was to evaluate its potential for the treatment of psoriasis. In vitro permeation through the psoriatic skin was carried out, and the results revealed that the combination of NPs with NIC exhibited a significant synergistic effect on FK506 deposition within the psoriatic skin (3...

Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior...

Psoriatic patients have systemic inflammation as well as oxidative stress, which are associated with cardiovascular disorders such as atherosclerosis, hypertension myocardial infarction, and stroke. Psoriasis has also been shown to be associated with kidney disease in several studies. Both disorders also have strong component of oxidative stress which usually emanates from NADPH oxidases (NOXs) and inducible nitric oxide synthase (iNOS). However, whether psoriatic inflammation leads to renal oxidative stress and dysfunction remains unexplored...

Psoriasis is a chronic inflammatory skin disease mediated by dysregulated auto-reactive immune system. In this study, in order to confirm and further extend the pharmacological basis of topical steroids in psoriasis therapy, we investigated the effect of betamethasone ointment on imiquimod (IMQ)-induced skin inflammation in mice. In BALB/c mice, topical IMQ at the dose of 250 µg each on both sides of the ear induced marked psoriasis-like skin inflammation within 5 days. The same dose of IMQ produced only slight to moderate skin inflammation even on Day 7 in CB-17 scid mice...
