Melphalan, Antimelanoma Immunity, and Inflammation--Response.

Combination central tolerance and peripheral checkpoint blockade unleashes antimelanoma immunity.

Blockade of immune checkpoint proteins (e.g., CTLA-4, PD-1) improves overall survival in advanced melanoma; however, therapeutic benefit is limited to only a subset of patients. Because checkpoint blockade acts by "removing the brakes" on effector T cells, the efficacy of checkpoint blockade may be constrained by the limited pool of melanoma-reactive T cells in the periphery. In the thymus, aut...

Activation Immunity through Localized TLR7/8 Effective Innate and Adaptive Antimelanoma

De Novo Chemoattractants Form Supramolecular Hydrogels for Immunomodulating Neutrophils In Vivo

Most immunomodulatory materials (e.g., vaccine adjuvants such as alum) modulate adaptive immunity, and yet little effort has focused on developing materials to regulate innate immunity, which get mentioned only when inflammation affects the biocompatibility of biomaterials. Traditionally considered as short-lived effector cells from innate immunity primarily for the clearance of invading microo...

Human activated macrophages and hypoxia: a comprehensive review of the literature

Macrophages accumulate in poorly vascularised and hypoxic sites including solid tumours, wounds and sites of infection and inflammation where they can be exposed to low levels of oxygen for long periods. Up to date, different studies have shown that a number of transcription factors are activated by hypoxia which in turn activate a broad array of mitogenic, pro-invasive, pro-angiogenic, and pro...

Therapy-induced antitumor vaccination by targeting tumor necrosis factor alpha to tumor vessels in combination with melphalan.

Treatment of tumor-bearing mice with mouse (m)TNF-alpha, targeted to tumor vasculature by the anti-ED-B fibronectin domain antibody L19(scFv) and combined with melphalan, induces a therapeutic immune response. Upon treatment, a highly efficient priming of CD4+ T cells and consequent activation and maturation of CD8+ CTL effectors is generated, as demonstrated by in vivo depletion and adoptive c...
