Antibiobodies are paradigmatic of yeast killer toxin (KT)-like antibodies (KAbs) mimicking the antimicrobial activity of KTs in the frame of the yeast killer phenomenon. Polyclonal, monoclonal and recombinant anti-idiotypic ...

Peptides are remarkably reactive molecules produced by a great variety of species and able to display a number of functions in uni-and multicellular organisms as mediators, agonists and regulating substances. Some of them ...

Natural killer cells constitute a population of lymphocytes able to non-specifically destroy virus-infected and some kinds of tumor cells. Since this lytic activity was shown by non-immunized animals the phenomenon is ...

We studied the effect of methionine-enkephalin (MET) and β-endorphin upon human peripheral blood lymphocyte natural killer cell (NKC) activity in a group of healthy volunteers (n = 27; 17 male and 10 female, age ± SD and ...

Vaccine-based cancer immunotherapy has generated highly variable clinical results due to differing methods of vaccine preparation and variation in patient populations among other lesser factors. Moreover, these clinical ...

Natural killer cells constitute a population of lymphocytes able to non-specifically destroy virus-infected and some kinds of tumor cells. Since this lytic activity was shown by non-immunized animals the phenomenon is ...

ProblemThe immune cellular composition of amniotic fluid is poorly understood. Herein, we determined: 1) the immunophenotype of amniotic fluid immune cells during the second and third trimester in the absence of intra-amniotic ...

Antimicrobial peptides are essential components of innate defense mechanisms and make promising candidates for novel anti-infective agents. The advantages of these peptides in clinical applications include their potential ...
