Abstract
Systemic treatment with hedgehog inhibitors (HHis) is available to treat basal cell carcinomas but their utility is limited by adverse effects. Topical delivery methods may reduce adverse effects, but successful topical treatment depends on sufficient skin uptake, biological response, and time in tumor tissue. The aim of this review was to evaluate the current status of topical HHi delivery for BCCs and discuss barriers for translating systemic HHis into topical treatments. A literature search identified 16 preclinical studies and 7 clinical trials on the topical delivery of 12 HHis that have been clinically tested on BCCs. Preclinical studies on drug uptake demonstrated that novel formulations, and delivery- and pre-treatment techniques enhanced topical HHi delivery. Murine studies showed that the topical delivery of sonidegib, itraconazole, vitamin D₃ and CUR-61414 led to biological responses and tumor remission. In clinical trials, only topical patidegib and sonidegib led to at least a partial response in 26/86 BCCs and 30/34 patients, respectively. However, histological clearance was not observed in the samples analyzed. In conclusion, the incomplete clinical response could be due to poor HHi uptake, biodistribution or biological response over time. Novel topical delivery techniques may improve HHi delivery, but additional research on cutaneous pharmacokinetics and biological response is needed.

Abstract
BACKGROUND High-intensity ultrasound has been used to induce acoustic cavitation in the skin and subsequently enhances skin permeability to deliver hydrophobic topical medications including lidocaine. In contrast, instead of changing skin permeability, pulsed application of low-intensity focused ultrasound (FUS) has shown to non-invasively and temporarily disrupt drug-plasma protein binding, thus has potential to enhance the anesthetic effects of hydrophilic lidocaine hydrochloride through unbinding it from serum/interstitial α1-acid glycoprotein (AAG). METHODS FUS, operating at fundamental frequency of 500 kHz, was applied pulse-mode (55-ms pulse duration, 4-Hz pulse repetition frequency) at a spatial-peak pulse-average intensity of 5 W/cm2. In vitro equilibrium dialysis was performed to measure the unbound concentration of lidocaine (lidocaine hydrochloride) from dialysis cassettes, one located at the sonication focus and the other outside the sonication path, all immersed in phosphate-buffered saline solution containing both lidocaine (10 µg/mL) and human AAG (5 mg/mL). In subsequent animal experiments (Sprague-Dawley rats, n = 10), somatosensory evoked potential (SSEP), elicited by electrical stimulations to the unilateral hind leg, was measured under three experimental conditions-applications of FUS to the unilateral thigh area at the site of administered topical lidocaine, FUS only, and lidocaine only. Skin temperature was measured before and after sonication. Passive cavitation detection was also performed during sonication to evaluate the presence of FUS-induced cavitation. RESULTS Sonication increased the unbound lidocaine concentration (8.7 ± 3.3 %) from the dialysis cassette, compared to that measured outside the sonication path (P < 0.001). Application of FUS alone did not alter the SSEP while administration of lidocaine reduced its P23 component (i.e., a positive peak at 23 ms latency). The FUS combined with lidocaine resulted in a further reduction of the P23 component (in a range of 21.8 - 23.4 ms after the electrical stimulations; F(2,27) = 3.2 - 4.0, P < 0.05), indicative of the enhanced anesthetic effect of the lidocaine. Administration of FUS neither induced cavitation nor altered skin conductance or temperature, suggesting that skin permeability was unaffected. CONCLUSIONS Unbinding lidocaine from the plasma proteins by exposure to non-thermal low-intensity ultrasound is attributed as the main mechanism behind the observation.

Abstract
BACKGROUND AND OBJECTIVE Hedgehog inhibitors such as vismodegib are targeted drugs widely used for the treatment of basal cell carcinomas; however, their use is significantly limited by frequent systemic side effects due to oral administration route. We aim to use ablative fractional laser (AFL) to enable the topical delivery of vismodegib to relevant dermal depths. MATERIALS AND METHODS Pig skin was treated in vitro with a fractional 10,600 nm CO2 laser at 0 or 80 mJ/microbeam and exposed to vismodegib (6.4 mmol/L) in Franz-diffusion cells for 0.5, 4, and 24 hours (n = 54 samples), either formulated in a micro-emulsion composed of soybean oil and Tween 80 or dissolved in ethanol as vehicle control. Vismodegib biodistribution was studied at specific skin depths from 0 to 1,800 µm (incremental steps of 300 µm) by mass spectrometry. RESULTS Combination of AFL and vismodegib emulsion substantially enhanced the delivery of drug into the skin. Emulsion formulation alone yielded higher vismodegib skin concentrations compared to vehicle control in superficial and mid-dermis (0-900 µm, P = 0.002-0.015). The over-all highest concentration found (554.5 µmol/L) was reached at 24 hours in superficial (0-300 µm) AFL exposed skin, 7.6-fold higher than vehicle control (P = 0.002) and 9.7-101.6 fold higher than previously reported steady-state plasma concentrations in patients treated with oral vismodegib (5.5-56.9 µmol/L). Compared to intact skin, AFL exposure significantly increased skin concentrations of vismodegib even in deep skin layers (24 h, 900-1,800 µm, emulsion: 8.7-74.3 µmol/L vs. 0.0-0.0 µmol/L, P = 0.004-0.048; vehicle control: 23.7-50.6 µmol/L vs. 0.0-1.6 µmol/L, P = 0.002). The total delivery of vismodegib-emulsion into mid-deep dermal skin layers from 600 to 1,800 µm was for AFL exposed skin 8.2 fold higher than intact skin. Also, delivery of emulsion vismodegib by AFL was time-dependent as seen by the continuous increase in concentrations found over time, with highest uptake detected after 24 hours (4-24 hours, 0-900 µm, P = 0.002-0.004). CONCLUSION AFL enhances topical delivery of micro-emulsion formulated vismodegib, reaching concentrations similar to or above plasma concentrations previously reported in patients receiving oral vismodegib.

Abstract
Early diagnosis is important for effective disease management. Measurement of biomarkers present at the local level of the skin could be advantageous in facilitating the diagnostic process. The analysis of the proteome of suction blister fluid, representative for the interstitial fluid of the skin, is therefore a desirable first step in the search for potential biomarkers involved in biological pathways of particular diseases. Here, we describe a global analysis of the suction blister fluid proteome as potential body fluid for biomarker proteins. The suction blister fluid proteome was compared with a serum proteome analyzed using identical protocols. By using stringent criteria allowing less than 1% false positive identifications, we were able to detect, using identical experimental conditions and amount of starting material, 401 proteins in suction blister fluid and 240 proteins in serum. As a major result of our analysis we construct a prejudiced list of 34 proteins, relatively highly and uniquely detected in suction blister fluid as compared to serum, with established and putative characteristics as biomarkers. We conclude that suction blister fluid might potentially serve as a good alternative biomarker body fluid for diseases that involve the skin.

Abstract
Langerhans cells (LC), the best-understood antigen presenting cells (APC) of the skin, are functionally plastic. Freshly obtained LC readily activate allogeneic T cells, but are incapable of activating autologous, naive T cells. When placed in culture in the presence of GM-CSF, LC up-regulate surface expression of class I and II MHC molecules along with co-stimulatory molecules, such as B7, CD40 and IL-12. This functional transformation enables the cells to activate naive, autologous T cells in vitro. It is paradoxical that intracutaneous administration of exogenous GM-CSF fails to induce intraepidermal LC to undergo functional transformation in situ. It has been reported that serum contains a factor that prevents fresh LC from undergoing functional transformation in culture, and the relevant serum factor has now been identified as haptoglobin (Hp), based on the following experimental results: (a) SDS-PAGE, amino acid sequencing, and mass spectrometric analyses of the inhibitory factor purified by high performance liquid chromatography (HPLC) from normal human serum revealed molecules completely homologous to Hp alpha-1 chain; (b) pure human Hp, but not serum depleted of Hp, inhibited fresh LC from acquiring the capacity to activate autologous T cells in vitro; (c) abundant Hp was detected in cytoplasmic compartments of fresh, but not cultured, LC. It was concluded that Hp, an acute phase protein, is a systemically-derived factor that prevents epidermal LC from spontaneously undergoing functional maturation in the skin. This novel property of Hp may be important in ameliorating or preventing certain T cell-dependent inflammatory skin diseases.

Abstract
BACKGROUND Previous studies showed that the currently used dextrose based peritoneal dialysis fluids impair several leucocyte functions. AIMS To determine which in vitro mononuclear leucocyte (monocyte) function tests most clearly reflect the biocompatibility of peritoneal dialysis fluid. METHODS Monocytes were tested for phagocytic capacity, bactericidal activity, Fc and C3 receptor expression, and chemiluminescence response, and by analysis of the release of interleukin 8 (IL-8) and tumour necrosis factor alpha (TNF alpha) in the presence of test fluids. Cytokine release was studied in an alternative dynamic in vitro peritoneal dialysis model in which monocytes were exposed to test fluid that was continuously equilibrated with an interstitial fluid-like medium through a microporous membrane. The chemiluminescence response by stressed monocytes was also tested after an 18 h recovery period. All tests were performed during or after exposure to different degrees of glycerol induced osmotic stress and after exposure to a 1% milk-whey derived, polypeptide enriched test fluid. Cells incubated in 0.1% gel Hanks buffer (GH) served as control. RESULTS Osmotic stress induced impairment of leucocyte function was found by the chemiluminescence assay (mean (SEM): 179 (20)% v 138 (23)% after 30 minutes in 0.5% and 1.5% glycerol, respectively) and by the analysis of IL-8 released by monocytes (44 (9) ng in 0.7% glycerol v 40 (7) ng in 2.0% glycerol). Only the chemiluminescence assay showed a protective effect of polypeptides on leucocyte function (after > or = 60 minutes). If monocytes were allowed to recover in culture medium after exposure to test fluids, the changes in chemiluminescence response appeared to be reversible after a 30 minute exposure, but became more pronounced after 60 and 120 minutes. The phagocytosis and bacterial killing assays were less sensitive. The observations carried out with the phagocytosis assay did not correspond with the Fc or C3 receptor density data. CONCLUSIONS The release of IL-8 by peripheral blood monocytes in a two compartment model and their chemiluminescence response are appropriate assays for the assessment of changes in leucocyte function in response to different peritoneal dialysis fluids.

Abstract
Cultured cells of various origins have been shown to be surrounded by a hyaluronan-containing coat, a structure that can be visualized by its ability to exclude large particles such as erythrocytes. When cultured in medium with no or low concentrations of serum, the cells lose their coats, although they still produce hyaluronan; upon the addition of serum, the coats are formed again. Here, we show that the serum protein inter-alpha-inhibitor can replace whole serum as an inducer of the formation of the coats on fibroblasts and mesothelial cells. The physiological role of inter-alpha-inhibitor has so far been unclear; our findings, together with those obtained with cumulus cell-oocyte complexes (Chen, L., Mao, S.J., and Larsen, W. J. (1992) J. Biol. Chem. 267, 12380-12386), suggest that inter-alpha-inhibitor and related proteins have a general function as stabilizers of hyaluronan-containing pericellular coats.
