Sphingosine‐1‐Phosphate Promotes FOS Activation in Osteosarcoma Under Tumor Acidosis

open access: yesActa Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim The tumor microenvironment in solid tumors is characterized by extracellular acidosis, which promotes cancer aggressiveness. In osteosarcoma, the most common primary bone cancer, a highly acidic tumor microenvironment is associated with metastasis and poor prognosis, partly due to metabolic rewiring, including changes in lipid pathways ...

Inflammatory Mediators Both Directly and Indirectly Promote Microglial Proliferation

open access: yesGlia, Volume 74, Issue 5, May 2026.
– CSF2, IL3, and TNFɑ directly promote microglial proliferation. – Neuron‐secreted factors suppress microglial proliferation. – IL1 cytokines promote CSF2 release from astrocytes, which promotes microglial proliferation. ABSTRACT Microglia—the predominant immune cell of the central nervous system (CNS)—possess an astounding capacity for proliferation ...

Pouch Surgery for Ulcerative Colitis: Navigating Complexity in the Modern Era

open access: yesJCC Plus, Volume 1, Issue 3, May 2026.
ABSTRACT Restorative proctocolectomy with ileal pouch–anal anastomosis (IPAA) remains the preferred surgical treatment for patients with ulcerative colitis (UC) who require surgery but wish to avoid a permanent ileostomy. Since its introduction in 1978, IPAA has undergone continuous refinement in response to advances in both medical therapy and ...

Innate Lymphoid Cells in Tissue Homeostasis and Diseases

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Innate lymphoid cells (ILCs) are a heterogeneous group of immune cells with phenotypic and functional plasticity. ILCs dynamically regulate various immune cell types and play a crucial role in the pathophysiological processes of specific organs during sepsis. Targeting ILCs is a promising strategy for treating sepsis.

Sphingosine‐1‐Phosphate Receptor 3 Confers Tumor Metastasis in Lung Cancer Resistant to Third‐Generation EGFR Inhibitor

open access: yesMedComm, Volume 7, Issue 5, May 2026.
• S1PR3 drives metastasis in EGFR TKI‐resistant lung cancer by activating RAC1‐PAK1 signaling and promoting EMT. • FGFR1‐STAT4 axis upregulates S1PR3, enabling metastatic escape in resistant tumors. • Targeting S1PR3 or FGFR1 suppresses metastasis, offering a therapeutic strategy for EGFR TKI‐resistant lung cancer.

Upregulation of sphingomyelin and ABCA8 in response to TDP‐43 pathology in amyotrophic lateral sclerosis brain

open access: yesBrain Pathology, Volume 36, Issue 3, May 2026.
Increases in sphingomyelin in response to TDP‐43 pathology in the disease‐affected motor cortex of amyotrophic lateral sclerosis (ALS) brain. Abstract Amyotrophic lateral sclerosis (ALS) is a rapidly progressing neurodegenerative disease characterized by the degeneration of motor neurons and the presence of TAR DNA‐binding protein 43 (TDP‐43 ...

From Development to Aging: Dynamic Roles of the Thymic Medulla in T Cell Biology

open access: yesImmunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT The thymic medulla is essential for establishing central tolerance, orchestrating the development of a diverse yet self‐tolerant T cell repertoire, and preventing autoimmunity. This process is primarily mediated through interactions between developing thymocytes and antigen‐presenting cells, including thymic epithelial cells (TECs) and ...
