Quality by design (QbD) accredited rutin-loaded self-nanoemulsifying system of krill oil for improved dissolution rate, ameliorating human neuroblastoma and hyperlipidemia.

Rutin (RU) and krill oil (KO) offer antioxidant synergism against free radicals generated during oxidative stress. RU/KO confers anti-hyperlipidemic, anti-inflammatory and pro-apoptotic actions following alternative pathways. However, their poor aqueous solubility/miscibility (RU/KO) affects the dissolution, dispersibility and low bioavailability.

MYD88 L265P mutations identify a prognostic gene expression signature and a pathway for targeted inhibition in CLL.

The L265P somatic mutation in the Myeloid Differentiation Primary Response 88 (MYD88) gene is a recurrent mutation in chronic lymphocytic leukaemia (CLL). This mutation has functional effects in various haematological malignancies but its role in CLL remains to be fully elucidated. Here, we report that MYD88 L265P mutations are associated with mutated immunoglobulin heavy-chain gene (IGHV-M) status and that among IGHV-M patients, the presence of MYD88 L265P is associated with younger age at diagnosis.

In vitro And In vivo Immunomodulating Properties of Mesenchymal Stem Cells.

Selective interleukin-1 receptor-associated kinase 4 inhibitors for the treatment of autoimmune disorders and lymphoid malignancy.

Pathological activation of the Toll-like receptor signaling adaptor protein MYD88 underlies many autoimmune and inflammatory disease states. In the activated B cell-like (ABC) subtype of diffuse large B cell lymphoma (DLBCL), the oncogenic MYD88 L265P mutation occurs in 29% of cases, making it the most prevalent activating mutation in this malignancy. IRAK4 kinase accounts for almost all of the biological functions of MYD88, highlighting IRAK4 as a therapeutic target for diseases driven by aberrant MYD88 signaling.

IL-33 synergizes with IgE-dependent and IgE-independent agents to promote mast cell and basophil activation.

Objective: Mast cell and basophil activation contributes to inflammation, bronchoconstriction, and airway hyperresponsiveness in asthma. Because IL-33 expression is inflammation inducible, we investigated IL-33-mediated effects in concert with both IgE-mediated and IgE-independent stimulation.

Methods: Because the HMC-1 mast cell line can be activated by GPCR and RTK signaling, we studied the effects of IL-33 on these pathways.
