Spleen tyrosine kinase (Syk) is a cytoplasmic protein tyrosine kinase well known for its ability to couple immune cell receptors to intracellular signaling pathways that regulate cellular responses to extracellular antigens and antigen-immunoglobulin (Ig) complexes of particular importance to the initiation of inflammatory responses. Thus, Syk is an attractive target for therapeutic kinase inhibitors designed to ameliorate the symptoms and consequences of acute and chronic inflammation. Its more recently recognized role as a promoter of cell survival in numerous cancer cell types ranging from leukemia to retinoblastoma has attracted considerable interest as a target for a new generation of anticancer drugs. This review discusses the biological processes in which Syk participates that have made this kinase such a compelling drug target.

Mechanistic exploration of Traditional Chinese Medicine regulation on tumor immune microenvironment in the treatment of triple-negative breast cancer: based on CiteSpace and bioinformatics analysis.
Front Immunol
January 2025
Department of Breast and Thyroid Surgery, Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Jinan, China.
Background: Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer, characterized by frequent recurrence, metastasis, and poor survival outcomes despite chemotherapy-based treatments. This study aims to investigate the mechanisms by which Traditional Chinese Medicine (TCM) modulates the tumor immune microenvironment in TNBC, utilizing CiteSpace and bioinformatics analysis.
Methods: We employed CiteSpace to analyze treatment hotspots and key TCM formulations, followed by bioinformatics analysis to identify the main active components, targets, associated pathways, and their clinical implications in TNBC treatment.
The dilemma of X-linked agammaglobulinemia carriers.
J Allergy Clin Immunol Glob
February 2025
Department of Molecular Medicine, Sapienza University, Rome, Italy.
Background: Many patients with X-linked agammaglobulinemia (XLA) nowadays have reached adulthood, as well as their sisters, possibly carriers of a deleterious Bruton tyrosine kinase variant. Studies on motherhood outcomes in families with XLA are lacking.
Objective: We sought to investigate adherence to carrier status screening, interest in preconception and prenatal genetic counseling, and reproductive decisions in relatives with XLA.
Lazertinib: breaking the mold of third-generation EGFR inhibitors.

Small molecules targeting activating mutations within the epidermal growth factor receptor (EGFR) are efficacious anticancer agents, particularly in non-small cell lung cancer (NSCLC). Among these, lazertinib, a third-generation tyrosine kinase inhibitor (TKI), has recently gained FDA approval for use in combination with amivantamab, a dual EGFR/MET-targeting monoclonal antibody. This review delves into the discovery and development of lazertinib underscoring the improvements in medicinal chemistry properties, especially in comparison with osimertinib.

Background: Treatment options for patients with high-risk metastatic clear cell renal cell carcinoma (mccRCC) include immune checkpoint inhibitors and tyrosine kinase inhibitors (TKIs), but clinical manifestations and treatment of these patients are rarely reported because patients with cardiac metastases and abrupt circulatory disorders are very rare and there are no precise guidelines to follow. In this study, we analyzed and discussed the clinical characteristics, related characteristics, pathogenesis and treatment strategies of patients with cardiac metastases of kidney cancer, so as to provide reference for the diagnosis and treatment of cardiac metastatic tumors.
Case Description: The patient was diagnosed with renal cell carcinoma and underwent surgical radical resection, no special treatment was performed after surgery.
Afatinib and Necitumumab in -Mutant NSCLC with Acquired Resistance to Tyrosine Kinase Inhibitors.
JTO Clin Res Rep
February 2025
Department of Medicine, Division of Oncology, Stanford University, Stanford, California.
Introduction: Although tyrosine kinase inhibitors (TKIs) are effective against NSCLC harboring sensitizing gene mutations, acquired resistance is inevitable. Preclinical studies suggest that combining EGFR TKI and monoclonal antibody therapies may have activity in mutated NSCLC that has progressed on TKI therapy alone. Therefore, we prospectively evaluated afatinib plus necitumumab in patients with mutated NSCLC.
