ICOS-Deficient Regulatory T Cells Can Prevent Spontaneous Autoimmunity but Are Impaired in Controlling Acute Inflammation.

J Immunol 2022 Jun 27. Epub 2022 Jun 27.

Institut de Recherches Cliniques de Montréal, Montreal, QC, Canada;

ICOS is induced in activated T cells and its main role is to boost differentiation and function of effector T cells. ICOS is also constitutively expressed in a subpopulation of Foxp3 regulatory T cells under steady-state condition. Studies using ICOS germline knockout mice or ICOS-blocking reagents suggested that ICOS has supportive roles in regulatory T (Treg) cell homeostasis, migration, and function. Read More

Providing organic macro minerals and an elevated platform improved tibia characteristics, and increased locomotion and performance of fast- and slower-growing broilers.

Poult Sci 2022 May 21;101(8):101973. Epub 2022 May 21.

Wageningen Livestock Research, Wageningen University and Research, PO Box 338, 6700 AH Wageningen, The Netherlands.

Improving leg health will support broiler health and welfare. Known factors to improve leg health are: replacing inorganic by organic macro minerals in the diet, providing environmental enrichments and using slower-growing broilers. However, it remains unknown how fast- and slower-growing broilers respond to a combination of providing organic macro minerals and an elevated platform as enrichment with regard to leg health.

Confirmatory Virucidal Activity of Ionised Active Water S-100® on the SARS-CoV-2 Virus.

Adv Virol 2022 17;2022:5995775. Epub 2022 Jun 17.

Aix Marseille University, IRD, AP-HM, MEPHI, 13005 Marseille, France.

Ionised active water S-100® has been proposed as an original solution for use in dermocosmetics and for the treatment of wounds such as burns and atopic dermatitis. Among the mechanisms of action that are not completely understood, an antimicrobial activity would appear to be important. In the context of the COVID-19 pandemic, we assessed the inactivating efficacy of this solution on SARS-CoV-2 based on the recommendations of the NF-EN-14476+A2 standard. Read More

Anticancer treatments and photosensitivity.

Authors:
V Sibaud

J Eur Acad Dermatol Venereol 2022 Jun;36 Suppl 6:51-58

Oncodermatology Department, Claudius REGAUD Institute and Cancer University Institute, Toulouse Oncopole, Toulouse Cedex 9, France.

Drug-induced photosensitivity is associated with a wide range of anticancer treatments, including conventional chemotherapeutic agents, targeted anticancer therapies, and immune checkpoint inhibitors. These dermatologic adverse events can have a major impact on the well-being and quality of life of cancer patients, leading to dose modifications and interruption or discontinuation of anticancer treatments in severe cases. However, the heterogeneous nature of the photosensitive reactions induced by these agents, as well as the common concomitant use of other potentially photosensitizing drugs (antibiotics, voriconazole, nonsteroidal anti-inflammatory drugs, etc. Read More

Role of IL-36 cytokines in psoriasis and other inflammatory skin conditions.

Cytokine 2022 Aug 6;156:155897. Epub 2022 Jun 6.

Immunology Discovery, Janssen Research and Development, San Diego, CA 92121, USA. Electronic address:

The IL-36 family of cytokines includes three pro-inflammatory agonists (IL-36α, IL-36β, and IL-36γ) and a receptor antagonist (IL-36Ra), which bind and signal through a heterodimeric receptor composed of IL-36R and the IL-1R accessory protein (IL-1RAcP). Individuals with inactivating mutations in the gene encoding IL-36Ra develop generalized pustular psoriasis, a severe form of psoriasis, a finding which clearly links dysregulated IL-36 pathway activation to inflammatory skin conditions. The purpose of this review is to highlight the cellular source of IL-36 cytokines, the effects of IL-36 signaling across cell types, and the association of IL-36 to a spectrum of inflammatory skin diseases including various forms of psoriasis as well as hidradenitis suppurativa, atopic dermatitis, and allergic contact dermatitis.
