JAK Inhibitors for Treatment of Psoriasis: Focus on Selective TYK2 Inhibitors
Drugs https://doi.org/10.1007/s40265-020-01261-8 CURRENT OPINION JAK Inhibitors for Treatment of Psoriasis: Focus on Selective TYK2 Inhibitors Miguel Nogueira1 · Luis Puig2 · Tiago Torres1,3 © Springer Nature Switzerland AG 2020 Abstract Despite advances in the treatment of psoriasis, there is an unmet need for efective and safe oral treatments. The Janus Kinase– Signal Transducer and Activator of Transcription (JAK–STAT) pathway plays a signifcant role in intracellular signalling of cytokines of numerous cellular processes, important in both normal and pathological states of immune-mediated infamma- tory diseases. Particularly in psoriasis, where the interleukin (IL)-23/IL-17 axis is currently considered the crucial pathogenic pathway, blocking the JAK–STAT pathway with small molecules would be expected to be clinically efective. However, relative non-specifcity and low therapeutic index of the available JAK inhibitors have delayed their integration into the therapeutic armamentarium of psoriasis. Current research appears to be focused on Tyrosine kinase 2 (TYK2), the frst described member of the JAK family. Data from the Phase II trial of BMS-986165—a selective TYK2 inhibitor—in psoriasis have been published and clinical results are encouraging, with a large Phase III programme ongoing. Further, the selective TYK2 inhibitor PF-06826647 is being tested in moderate-to-severe psoriasis in a Phase II clinical trial. Brepocitinib, a potent TYK2/JAK1 inhibitor, is also being evaluated, as both oral and topical treatment. Results of studies with TYK2 inhibitors will be important in assessing the clinical efcacy and safety of these drugs and their place in the therapeutic armamentarium of psoriasis. -
Stem Cell/Wnt
Inhibitors, Agonists, Screening Libraries www.MedChemExpress.com Stem Cell/Wnt Stem cells are required for continuous tissue maintenance within diverse organs, stem cell activity is often externally dictated by the microenvironment (the niche) so that stem cell output is precisely shaped to meet homeostatic needs or regenerative demands. Several key signaling pathways have been shown to play essential roles in this regulatory capacity. Specifically, the JAK/STAT, Hedgehog, Wnt, Notch, Smad, PI3K/phosphatase and tensin homolog, and NK-κB signaling pathways have all been shown experimentally to mediate various stem cell properties, such as self-renewal, cell fate decisions, survival, proliferation, and differentiation. Recent studies mainly focus on cancer stem cell, induced pluripotent stem cell, neural stem cell and maintenance of embryonic stem cell pluripotency. Cancer stem cells (CSCs) have been believed to be responsible for tumor initiation, growth, and recurrence. Numerous agents have been developed to specifically target CSCs by suppressing the expression of pluripotency maintaining factors Nanog, Oct-4, Sox-2, and c-Myc and transcription of GLI. Induced pluripotent stem cells (iPSCs) have the capacity to differentiate into various types of cells, and a self-renewing resource, and scientists can experiment with an unlimited number of pluripotent cells to perfect the process of targeted differentiation, transplantation, and more, for personalized medicine. Novel pathological mechanisms have been elucidated, new drugs originating from iPSC screens are in the pipeline and the first clinical trial using human iPSC-derived products has been initiated.

Poison Ivy (Toxicodendron Radicans) DESCRIPTION
Weed Identification and Control Sheet: www.goodoak.com/weeds Poison Ivy (Toxicodendron radicans) DESCRIPTION: Poison ivy is a native woody vine and member of the sumac family. It can be found in shady and sunny sites rambling along the ground, forming a small shrub, or climbing up trees. The vines attach to surfaces by means of thin aerial roots which grow along the length of the stem. The plant always has three leaflets which are often serrated. Usually these leaflets have one dominant lobe, giving the outer two leaves the appearance of mittens with the central leaf resembling a mitten with two thumbs. Young leaves are often dark green or maroonish, and the attractive fall foliage can range from brick to fire- engine red. Poison ivy is generally not considered a threat to native plant communities, in fact, the white berries provide winter food for birds and deer relish the foliage. Though harmless to most animals, many humans are allergic to the urushiol (yoo-roo-shee-ol) oil produced by the plant which results in itching, inflammation and blisters. This oil is found in all parts of the plant during all times of the year. This oil can also be spread by contact with clothing, shoes, pets or equipment that have touched poison ivy weeks or months after initial contact. It can even be transmitted in the air when poison ivy is burned, which presents a severe risk if inhaled and has been known to result in hospitalization and death. Though some people are not alleargic to the oil, its important to wear pants, long sleeves and gloves when working around poison ivy since the allergy can develop af- ter repeated exposures to urushiol. -

In Vitro Studies of Poison Oak Immunity. I. in Vitro Reaction of Human Lymphocytes to Urushiol
In vitro studies of poison oak immunity. I. In vitro reaction of human lymphocytes to urushiol. V S Byers, … , N Castagnoli, H Baer J Clin Invest. 1979;64(5):1437-1448. https://doi.org/10.1172/JCI109602. Research Article Poison oak, ivy, and sumac dermatitis is a T-cell-mediated reaction against urushiol, the oil found in the leaf of the plants. This hapten is extremely lipophilic and concentrates in cell membranes. A blastogenesis assay employing peripheral blood lymphocytes obtained from humans sensitized to urushiol is described. The reactivity appears 1--3 wk after exposure and persists from 6 wk to 2 mon. The dose-response range is narrow, with inhibition occurring at higher antigen concentrations. Urushiol introduced into the in vitro culture on autologous lymphocytes, erythrocytes and heterologous erythrocytes produces equal results as measured by the optimal urushiol dose, the intensity of reaction, and the frequency of positive reactors. This suggests that the urushiol is passed from introducer to some other presenter cell. Although the blastogenically reactive cell is a T cell, there is also a requirement for an accessory cell, found in the non-T- cell population, for reactivity. Evidence is presented that this cell is a macrophage. Find the latest version: https://jci.me/109602/pdf In Vitro Studies of Poison Oak Immunity I.

Leaves of Three, Let It Be
Leaves of Three, Let It Be By Doug Coffey, Fairfax Master Gardener Intern My neighbor, an Iranian immigrant, decided to remove a large bush maybe 4 to 5 feet tall and nearly as wide between our properties. I had ignored it, knowing it was so covered in poison ivy that the original plant was unrecognizable. I decided it was better to leave the “bush” alone until I could figure out how to get rid of it. But my neighbor, not consulting with me and not knowing the risks, got out a shovel, dug it up, pulled it out, cut it into pieces and hauled it to the curb. Within Brandeia University hours, he was in the emergency room and then several days after in the hospital getting massive doses of photo: steroids. He was so uncomfortable with the extensive blistering, rash and itching that he couldn’t even find a way to sleep. Even thinking about it today makes my skin itch. !P!o!i!s!o!n! !i!v!y! !(!T!o!x!i!c!o!d!e!n!d!r!o!n! !r!a!d!i!c!a!n!s!)! !c!o!n!t!a!i!n!s! !a! !l!a!c!q!u!e!r!-!t!y!p!e! !o!i!l! !c!a!ll! !e!d! !u!r!u!s!h!i!o!l!,! !(!y!o!u!-!R!o!o!-!s!h!e!e!-!a!l!l!)! !t!h!a!t! !c!a!n! !c!a!u!s!e! !r!e!d!n!e!s!s!,! !s!w!e!l!l!i!n!g! !a!n!d! !b!l!i!s!t!e!r!s!.! ! !U!r!u!s!h!i!o!l! !i!s! !f!o!u!n!d! !i!n! !a!l!l! !p!a!r!t!s! !o!f! !t!h!e! !p!l!a!n!t! --! !t!h!e! !l!e!a!v!e!s!,! !s!t!e!m!s! !a!n!d! !e!v!e!n! !t!h!e! !r!o!o!t!s!,! !a!n!d! !i!s! !p!a!r!t! !o!f! !t!h!e! !p!l!a!n!t’!s! !d!e!f!e!n!s!e! !a!g!a!i!n!s!t! !b!r!o!w!s!i!n!g! !a!n!i!m!a!l!s! !a!n!d! !h!u!m!a!n! !b!e!i!n!g!s! !w!h!o! !t!r!y! !t!o! !r!e!m!o!v!e! !i!t!.! !T!h!e! !o!i!l! !i!s! !m!o!s!t!l!y!
