Intrathymic expression of Flt3 ligand enhances thymic recovery after irradiation [PDF]

open access: yes, 2008
Hematopoietic stem cell transplantation (HSCT) requires conditioning treatments such as irradiation, which leads to a severely delayed recovery of T cell immunity and constitutes a major complication of this therapy.

Wedelolactone, a Novel TLR2 Agonist, Promotes Neutrophil Differentiation and Ameliorates Neutropenia: A Multi‐Omics Approach to Unravel the Mechanism

open access: yesAdvanced Science, EarlyView.
Wedelolactone (WED), a natural TLR2 agonist, promotes neutrophil differentiation and enhances bactericidal function, offering a potential therapeutic strategy for neutropenia. Using a multi‐omics approach, this study reveals that WED activates the TLR2/MEK/ERK pathway, upregulating key transcription factors (PU.1, CEBPβ) to drive neutrophil development.

A Case of Intratyhroidal Ectopic Thymus [Intratiroidal Ektopik Timus Olgusu]

open access: yesMedicine Science, 2015
Ectopic intrathyroidal thymus tissue is rare. Mostly it is seen in childhood as an asymptomatic thyroid nodule. It can be easily misdiagnosed as a benign or malignant thyroid nodule. Like thymus, it may regress in time. Ectopic thymus tissue can rarely

Diagnostic utility of LMO2 immunohistochemistry in distinguishing T-lymphoblastic leukemia/lymphoma from thymoma

open access: yesIndian Journal of Pathology and Microbiology, 2023
Distinguishing T-lymphoblastic leukemia/lymphoma (T-ALL/T-LBL) from thymomas (especially B1 or B2 type) can be challenging particularly in limited trucut biopsy material where appreciating architecture is difficult or the background epithelial component ...

A Systemic Selective Modified mRNA Delivery Platform for Preventing Chemotherapy‐Induced Cardiotoxicity

open access: yesAdvanced Science, EarlyView.
In Yoo and Mainkar et al., we present a minimally invasive, CM‐selective modRNA delivery system encapsulated in lipid nanoparticles for intravenous (IV) administration. This platform enables selective cardiac translation of therapeutic modRNA but suppresses expression in off‐target tissues, including tumors.

Aberrant cervical thymus and the role of ultrasonography: A case report

open access: yesThe Turkish Journal of Pediatrics, 2016
Ectopic/aberrant cervical thymic tissue is a rare cause of neck mass and usually detected incidentally. Aberrant thymic tissue can occur anywhere in the course of thymic descent from the angle of the mandible to the superior mediastinum. We report

Exclusive development of T cell neoplasms in mice transplanted with bone marrow expressing activated Notch alleles [PDF]

open access: yes, 1996
Notch is a highly conserved transmembrane protein that is involved in cell fate decisions and is found in organisms ranging from Drosophila to humans. A human homologue of Notch, TAN1, was initially identified at the chromosomal breakpoint of a subset of

Systematic study of constitutive cyclo-oxygenase-2 expression: role of NFκB and NFAT transcriptional pathways [PDF]

open access: yes, 2015
Cyclooxygenase-2 (COX-2) is an inducible enzyme that drives inflammation and is the therapeutic target for widely used nonsteroidal antiinflammatory drugs (NSAIDs).

CDK4/6 Inhibition Induces CD8+ T Cell Antitumor Immunity via MIF‐Induced Functional Orchestration of Tumor‐Associated Macrophages

open access: yesAdvanced Science, EarlyView.
CDK4/6 inhibition promotes CD8+ T cell expansion through tumor‐macrophage crosstalk by activating HIF‐1α and enhancing MIF‐CD44/CD74 signaling. This reprograms TAMs to boost MHC‐I antigen presentation, and CDK4/6 inhibitor‐trained M1 TAM supernatant therapy synergizes with low‐dose PD‐1 blockade to restore antitumor immunity.
