Chemokines and their receptors in oral squamous cell carcinoma: mechanisms, clinical significance, and therapeutic implications.

Chemokines, a category of cytokines exhibiting chemotactic properties, have been thoroughly investigated as targets in cancer treatment in recent decades. In oral squamous cell carcinoma (OSCC), a prevalent and high-risk malignancy of the head and neck, chemokines interact with their specific receptors to initiate downstream signaling pathways. This signaling influences not only tumor cell proliferation, migration, invasion, and metastasis of oral cancer cells but also angiogenesis and vascular maturation. Furthermore, they modulate the tumor microenvironment (TME), which consists of diverse c

Interleukin-1 Beta-A Friend or Foe in Malignancies?

Interleukin-1 beta (IL-1β) is induced by inflammatory signals in a broad number of immune cell types. IL-1β (and IL-18) are the only cytokines which are processed by caspase-1 after inflammasome-mediated activation. This review aims to summarize current knowledge about parameters of regulation of IL-1β expression and its multi-facetted role in pathophysiological conditions. IL-1 signaling activates innate immune cells including antigen presenting cells, and drives polarization of CD4+ T cells towards T helper type (Th) 1 and Th17 cells. Therefore, IL-1β has been attributed a largely beneficial

Strategies to overcome myeloid cell induced immune suppression in the tumor microenvironment.

Cancer progression and metastasis due to tumor immune evasion and drug resistance is strongly associated with immune suppressive cellular responses, particularly in the case of metastatic tumors. The myeloid cell component plays a key role within the tumor microenvironment (TME) and disrupts both adaptive and innate immune cell responses leading to loss of tumor control. Therefore, strategies to eliminate or modulate the myeloid cell compartment of the TME are increasingly attractive to non-specifically increase anti-tumoral immunity and enhance existing immunotherapies. This review covers cur

Role of Bruton's tyrosine kinase in B cells and malignancies.

Bruton's tyrosine kinase (BTK) is a non-receptor kinase that plays a crucial role in oncogenic signaling that is critical for proliferation and survival of leukemic cells in many B cell malignancies. BTK was initially shown to be defective in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential both for B cell development and function of mature B cells. Shortly after its discovery, BTK was placed in the signal transduction pathway downstream of the B cell antigen receptor (BCR). More recently, small-molecule inhibitors of this kinase have shown excellent anti-tumor a
