Introduction

Receptor for interleukin-12. This subunit is the signaling component coupling to the JAK2/STAT4 pathway. Promotes the proliferation of T-cells as well as NK cells. Induces the promotion of T-cells towards the Th1 phenotype by strongly enhancing IFN-gamma production.

Cottonseed meal and rapeseed meal exhibit a potential for fishmeal substitute in grass carp feed, while their excessive use contribute to growth decline and weakening immunity of aquatic animals. Clostridium butyricum metabolites (CBM) was recognized as a functional additive due to its antioxidant properties and maintenance of intestinal microbiota balance. CBM was added to a high of cottonseed and rapeseed meal diet to determine its effects on growth, immunity, and intestinal microbiota alterations of grass carp (Ctenopharyngodon idella) over 56 days. Eight hundred grass carp (mean weight, around 50 g) were randomized to five treatments and fed with the basic diet (CON), CBM0 diet (28 % cottonseed and 27 % rapeseed meal), and CBM diets (CBM0.5, CBM1, and CBM2, namely CBM0 diet supplemented with 500, 1000, and 2000 mg kg^-1 CBM). The results indicated that compared to CBM0, The ingestion of 1000 mg kg^-1 CBM diet by grass carp significantly promoted growth as measured by intestinal lipase activity, villus height, and muscle thickness. Moreover, accompanied by a decrease in intestine MDA content, and enhance antioxidant capacity by activating Keap1/Nrf2 signaling pathway to increase enzyme activities (SOD, CAT and T-AOC) and corresponding gene expression (mnsod, cat, gsto and gpx1) in the intestine of grass crap fed CBM1 diet. The dietary CBM1 diet increased serum levels of C3 and IgM, increased ACP activity and expression of the corresponding anti-inflammatory factors (tgf-β1 and il-15), and suppressed the expression of pro-inflammatory factors (tnf-α and il-12β), resulting in enhanced immunity. The dietary CBM1 diet up-regulates gene expression of tight junction proteins (zo-1, occludin, occludin7a and occludin-c), coupled with the decreases in DAO and D-lactate contents, implying that the decreased mucosal permeability could be observed in the gut. The dietary CBM1 diet largely altered the intestinal microbial community, especially reducing the relative abundance of intestinal pathogenic bacteria (Streptococcus and Actinomyces). And it significantly increased the content of short-chain fatty acids (acetic acid, butyric acid, isobutyric acid, propionic acid and isovaleric acid). Taken above, dietary CBM supplementation improved growth in grass carp and attenuated the intestinal oxidative stress, inflammation and microflora dysbacteriosis caused by high proportions of cottonseed and rapeseed meal diets.

Bimin Kang ameliorates the minimal persistent inflammation in allergic rhinitis by reducing BCL11B expression and regulating ILC2 plasticity

ETHNOPHARMACOLOGICAL RELEVANCEMinimal persistent inflammation (MPI) is a major contributor to the recurrence of allergic rhinitis (AR). The traditional Chinese herbal medicine known as Bimin Kang Mixture (BMK) have been used in clinics for decades to treat AR, which can relieve AR symptoms, reduce inflammatory response and improve immune function. However, its mechanism in controlling MPI is still unclear.AIM OF THE STUDYThis study aims to assess the therapeutic effect of BMK on MPI, and elaborate the mechanism involved in BMK intervention in BCL11B regulation of type 2 innate lymphoid cell (ILC2) plasticity in the treatment of MPI.MATERIAL AND METHODSThe effect of BMK (9.1 ml/kg) and Loratadine (15.15 mg/kg) on MPI was evaluated based on symptoms, pathological staining, and ELISA assays. RT-qPCR and flow cytometry were also employed to assess the expression of BCL11B, IL-12/IL-12Rβ2, and IL-18/IL-18Rα signaling pathways associated with ILC2 plasticity in the airway tissues of MPI mice following BMK intervention.RESULTSBMK restored the airway epithelial barrier, and markedly reduced inflammatory cells (eosinophils, neutrophils) infiltration (P < 0.01) and goblet cells hyperplasia (P < 0.05). BCL11B expression positively correlated with the ILC2 proportion in the lungs and nasal mucosa of AR and MPI mice (P < 0.01). BMK downregulated BCL11B expression (P < 0.05) and reduced the proportion of ILC2, ILC3 and ILC3-like ILC2 subsets (P < 0.05). Moreover, BMK promoted the conversion of ILC2 into an ILC1-like phenotype through IL-12/IL-12Rβ2 and IL-18/IL-18Rα signaling pathways in MPI mice.CONCLUSIONBy downregulating BCL11B expression, BMK regulates ILC2 plasticity and decreases the proportion of ILC2, ILC3, and ILC3-like ILC2 subsets, promoting the conversion of ILC2 to ILC1, thus restoring balance of ILC subsets in airway tissues and control MPI.

Structure and assembly of the human IL-12 signaling complex

Article

Author: Zeng, Jianwei ; Wang, Xinquan ; Ge, Xiaofei ; Li, Chun ; Chen, Huiqin

Interleukin (IL)-12 is a heterodimeric pro-inflammatory cytokine. Our cryoelectron microscopy structure determination of human IL-12 in complex with IL-12Rβ1 and IL-12Rβ2 at a resolution of 3.75 Å reveals that IL-12Rβ2 primarily interacts with the IL-12p35 subunit via its N-terminal Ig-like domain, while IL-12Rβ1 binds to the p40 subunit with its N-terminal fibronectin III domain. This binding mode of IL-12 with its receptors is similar to that of IL-23 but shows notable differences with other cytokines. Through structural information and biochemical assays, we identified Y62, Y189, and K192 as key residues in IL-12p35, which bind to IL-12Rβ2 with high affinity and mediate IL-12 signal transduction. Furthermore, structural comparisons reveal two distinctive conformational states and structural plasticity of the heterodimeric interface in IL-12. As a result, our study advances our understanding of IL-12 signal initiation and opens up new opportunities for the engineering and therapeutic targeting of IL-12.
