Brodalumab: Efficacy, safety, and survival in mid-term (52 weeks) on real clinical practice in Andalucia, Spain.
Brodalumab is a recombinant monoclonal antibody (IgG2) that binds with high affinity to the human interleukin-17 (IL-17) receptor A and blocks the biological activity of the proinflammatory cytokines IL-17A, IL-17F, IL-17A/F heterodimer, and IL- 25, resulting in inhibition of inflammation and clinical symptoms associated with psoriasis. Its introduction has managed to increase the levels of efficacy, safety (improving that previously presented by the anti-IL-17 class), and survival.Manuel Galan-Gutierrez, Pilar Font-Ugalde, Laura Padilla, Carlos Hernandez-Montoya, Daniel Godoy, Jose C Armario-Hita, Ricardo Ruiz-Villaverde

A Heterodimeric Cytokine, Consisting of IL-17A and IL-17F, Promotes Migration and Capillary-Like Tube Formation of Human Vascular Endothelial Cells.
The interleukin (IL)-17 family, consisting of six homodimeric cytokines IL-17A, IL-17B, IL-17C, IL-17D, IL-17E/IL-25, and IL-17F, mediates a variety of biological activities including regulation of chemokine secretion and angiogenesis. Among the IL-17 family members, IL-17A and IL-17E/IL-25 are angiogenesis stimulators, while IL-17B and IL-17F are angiogenesis inhibitors. Recently, IL-17A/F heterodimer, comprised of the IL-17A and IL-17F subunits, was found as another member of the IL-17 cytokine family. However, to date, it has been unknown whether IL-17A/F has biological actions to affect the angiogenesis-related vascular endothelial functions. Therefore, in this study, we investigated the biological effects of IL-17A/F on the growth, migration and capillary-like tube formation of vascular endothelial cells. Recombinant IL-17A/F protein had no direct effects on the growth of human dermal microvascular endothelial cells (HMVECs), whereas, after 4-hour incubation in a modified Boyden Chemotaxicell chamber, IL-17A/F significantly induced migration of HMVECs over a wide range of doses via the phosphatidylinositol-3 kinase (PI3K) signaling pathway. We further investigated the biological effect of IL-17A/F on capillary-like tube formation using a co-culture system of human umbilical vein endothelial cells (HUVECs) and human dermal fibroblasts (HDFs), which mimicked the in vivo microenvironment. In this co-culture system, IL-17A/F significantly promoted capillary-like endothelial tube formation in a dose-dependent fashion via the PI3K and extracellular signal-regulated kinase (ERK) signaling pathways. Additionally, IL-17A/F up-regulated secretion of angiogenic growth factors such as IL-8 and growth-related oncogene (GRO)-α by HDFs. These findings identify a novel biological function for IL-17A/F as an indirect angiogenic agent.Muneo Numasaki, Hiroki Tsukamoto, Yoshihisa Tomioka, Yasuhiko Nishioka, Takashi Ohrui

A novel heterodimeric cytokine consisting of IL-17 and IL-17F regulates inflammatory responses.
CD4+ helper T (TH) cells play crucial roles in immune responses. Recently a novel subset of TH cells, termed TH(IL-17), TH17 or inflammatory TH (THi), has been identified as critical mediators of tissue inflammation. These cells produce IL-17 (also called IL-17A) and IL-17F, two most homologous cytokines sharing similar regulations. Here we report that when overexpressed in 293T cells, IL-17 and IL-17F form not only homodimers but also heterodimers, which we name as IL-17A/F. Fully differentiated mouse THi cells also naturally secrete IL-17A/F as well as IL-17 and IL-17F homodimeric cytokines. Recombinant IL-17A/F protein exhibits intermediate levels of potency in inducing IL-6 and KC (CXCL1) as compared to homodimeric cytokines. IL-17A/F regulation of IL-6 and KC expression is dependent on IL-17RA and TRAF6. Thus, IL-17A/F cytokine represents another mechanism whereby T cells regulate inflammatory responses and may serve as a novel target for treating various immune-mediated diseases.Seon Hee Chang, Chen Dong
