BACKGROUND Cognate immunity against neoplastic cells depends on a balance between effector T cells and regulatory T (Treg) cells. Treg cells prevent immune attack against normal and neoplastic cells by directly suppressing the activation of effector CD4+ and CD8+ T cells. We postulated that a recombinant interleukin 2/diphtheria toxin conjugate (DAB/IL2;(More)
The role of complement in neonatal hypoxic-ischemic brain injury is not known. Therefore, cerebral spinal fluid (CSF) and post-mortem cerebral tissue were analyzed to determine whether complement is activated and complement component 9 (C9) is deposited on neurons in the central nervous systems (CNS) of newborn infants who developed moderate to severe(More)
Human serum contains 2 isoforms of type-5 tartrate-resistant acid phosphatase (TRACP): 5a and 5b. TRACP-5b is osteoclastic. Our goal was to determine if serum TRACP-5a could originate from inflammatory macrophages (MPhi). We stained 246 paraffin-embedded tissue samples for TRACP using monoclonal antibody 9C5 (mab9C5) to isoforms 5a and 5b and a novel mab220(More)
