Respiratory tract diseases and cytokine.

open access: yesNihon Naika Gakkai Zasshi, 1995
サイトカインは,リンパ球,マクロファージなどの細胞から産生される免疫反応・炎症を調節・制御する因子である.多種類のサイトカインが発見され,呼吸器疾患においてもサイトカインがその病態に関与する事が明らかとなり,あるいは治療に応用されている.主要サイトカインとしては,インターロイキン(IL-1~IL-10),インターフェロン,コロニー刺激因子(CSF),腫瘍壊死因子(TNF)などが知られている.肺線維症においては線維芽細胞増殖に対し, PDGFとIGF-Iが重要な働きをしている事が知られている.サルコイドーシスにおいては, TNF-α, IL-6, PDGF, GM-CSFが肺局所で増加し,肉芽腫形成に関与していると推測されている.気管支喘息では, IL-5は好酸球を活性化し, IgE産生については ...

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

open access: yesAdvanced Science, EarlyView.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...

Stromal Cell‐Mast Cell Communication Orchestrates Anti‐Viral Immunity in the Meninges

open access: yesAdvanced Science, EarlyView.
This study delineates the spatial distribution and postnatal maturation of meningeal mast cells and uncovers their essential role in antiviral immunity. Using genetic models, mast cells are shown to promote CD8⁺ T cell infiltration and viral clearance via IL‐33 receptor signaling and synergistic activation by IL‐33 and ATP from infected stromal cells ...
