BACKGROUND Efforts in search of lasting malaria vaccine have led to the development of transgenic rodent malaria parasites. As a result, wild type Plasmodium berghei ANKA (WTPbA) has recently been transformed to express mouse interferon gamma (mIFN-γ). The immunomodulatory effect of this transgenic parasite on WTPbA infection has been demonstrated. However, the protective immune responses after...

Dendritic cells (DCs) are potent antigen-presenting cells and play a pivotal role in T cell-mediated immunity. DCs have been shown to induce strong antitumor immune responses in vitro and in vivo, and their efficacy is being investigated in clinical trials. Compared with vaccination strategies directed against a single tumor antigen, tumor-cell lysate as the source of antigen offers the potenti...

This year celebrates the 30th anniversary of the licensing of Limulus amebocyte lysate (LAL) by the US Food and Drug Administration (FDA) as a test for the presence of endotoxin in biologicals, pharmaceutical drugs, and medical devices. LAL is currently recognized by several major pharmacopoeias and is used worldwide. That a suitable alternative for the detection of endotoxin has not supplanted...

1. Under optimal ionic conditions (4 mM-MnCl2) the specific activity of guanylate cyclase in fresh platelet lysates was about 10nmol of cyclic GMP formed/20 min per mg of protein at 30 degrees C. Activity was 15% of optimum with 10mM-MgCl2 and negligible with 4mM-CaCl2. Synergism between MnCl2 and MgCl2 or CaCl2 was observed when [MnCl2] less than or equal to [GPT]. 2. Lower than optimal specif...

Aim: To identify immunodominant proteins of cystic fluid antigens and whole cyst lysate antigens of Cysticercus tenuicollis, the larval stage of the canine tapeworm Taenia hydatigena. Materials and Methods: Three numbers of cysts of C. tenuicollis were collected from the mesentry of small intestine of goats after slaughter. C. tenuicollis cysts of each sample were washed thoroughly with PBS (pH...
