In rheumatoid arthritis, dysregulated cytokine signaling has been implicated as a primary factor in chronic inflammation. Many antirheumatic and biological therapies are used to suppress joint inflammation, but despite these advances, effectiveness is not universal, delivery often at high doses, which can predispose patients significant off-target effects. During the inappropriate regulation of factors by macrophages accelerates progression disease driving an imbalance inflammatory cytokines, making ideal cellular target. To develop macrophage-based therapy treat we engineered novel induced pluripotent stem cell (iPSC)-derived macrophage capable delivering soluble TNF receptor 1 (TNFR1), anti-inflammatory biologic inhibitor tumor necrosis alpha (TNF-α), auto-regulated manner response TNF-α. Murine iPSCs were differentiated into (iMACs) over 17-day optimized protocol with continued successful differentiation confirmed key timepoints. Varying immunomodulatory stimuli demonstrated traditional function phenotypes. TNF-α, therapeutic iMACs produced levels sTNFR1 autoregulated manner, inhibited signaling. This self-regulating iMAC system potential for drug approach variety diseases.

Cervical cancer (CC) is a serious global health issue, and it well-known that HPV infection the main etiological factor triggers carcinogenesis. In cancer, chemokine ligands receptors are involved in tumor cell growth, metastasis, leukocyte infiltration, angiogenesis; however, information on role played by E6/E7 of HPV16/18 modulation chemokines very limited. Therefore, this study aimed to determine whether differentially expressed CC-derived lines; if oncoproteins from HPV16 18 capable mediating expression, what expression profile tissues derived CC their impact overall survival patients with pathology? For purpose, RNA sequencing real-time PCR were performed SiHa, HeLa, C33A tumorigenic lines, non-tumorigenic HaCaT cells, HPV-transduced models. Furthermore, analysis executed 304 22 normal tissue samples The Cancer Genome Atlas (TCGA) repository. results demonstrate CXCL1, CXCL2, CXCL3, CXCL8 regulated 18, overexpressed biopsies, higher related worse prognostic survival.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignancies worldwide and has a poor prognosis. Although immune checkpoint inhibitors have entered new era HCC treatment, their response rates are modest, which can be attributed to immunosuppressive tumor microenvironment within tumors. Accumulating evidence shown that growth fueled by cancer stem cells (CSCs), contribute therapeutic resistance above treatments. Given CSCs regulate cellular physical factors niche secreting various soluble in paracrine manner, there been increasing efforts toward understanding roles CSC-derived secretory creating an microenvironment. In this review, we provide update on how these factors, including cytokines, chemokines, exosomes, TME, leads resistance. addition, present current strategies targeting describe future perspectives. summary, better CSC biology TME provides rational basis for combination therapy with ICIs effective treatment.
