The monocyte-macrophage lineage shows a high degree of diversity and plasticity. Once they infiltrate tissues, they may acquire two main functional phenotypes, being known as the classically activated type 1 macrophages (M1) and the alternative activated type 2 macrophages (M2). The M1 phenotype can be induced by bacterial products and interferon-γ and(More)
Tumor-associated macrophages (TAMs) are key elements in orchestrating host responses inside tumor stroma. This population may undergo a polarized activation process, thus rendering a heterogeneous spectrum of phenotypes, where the classically activated type 1 macrophages (M1) and the alternative activated type 2 macrophages (M2) represent two extreme(More)
BACKGROUND Orthostatic hypotension (OH) is a rare manifestation of medulla oblongata lesions that may be because of interruption of descending sympathoexcitatory axons. AIMS To illustrate the location of a medullary lesion that produced OH following resection in relationship to the location of putative sympathoexcitatory pathways. METHOD A case with(More)
