Cellular immune responses in the pathophysiology of preeclampsia
Journal of Leukocyte Biology, 2021AbstractPreeclampsia, defined as new-onset hypertension accompanied by proteinuria occurring at 20 weeks of gestation or later, is a leading cause of perinatal morbidity and mortality worldwide. The pathophysiology of this major multi-systemic syndrome includes defective deep placentation, oxidative stress, endothelial dysfunction, the presence of an ...

Cellular immune response in coccidioidomycosis
Cellular Immunology, 1975Abstract The CMI response in vitro and in vivo of 30 patients with a poor biologic response to infection with C. immitis was investigated. In patients with active pulmonary disease, skin reactivity to CDN was observed in 7 10 , and to at least one of five other antigens in 8 10 .

Cellular Immune Responses in Neonates
International Reviews of Immunology, 2000Reduced numbers of lymphocytes and antigen presenting cells have been described as some of the main factors responsible for antigenic tolerance or low responsiveness in neonates. However, by changing the parameters of immunization, such as dose of antigen and frequency of antigen presenting cells we and others have shown that neonates have the option ...

Redirecting the Cellular Immune Response
International Reviews of Immunology, 1989A technology is described which combines the power of T lymphocytes in eliminating unwanted cells and causing beneficial inflammatory reactions with the great advantages of monoclonal antibodies. We show that heteroconjugate antibodies and hybrid antibodies, in which one of the component binding sites is anti-T-cell receptor and the other component ...

Cellular immune responses in human neurocysticercosis
Parasitology Research, 2000Studies on the role of cell-mediated immune responses in human neurocysticercosis (NCC) are lacking. Various cell-mediated immune responses such as lymphocyte subpopulation, lymphocyte transformation to cysticercus antigens and cytokine profile were carried out in NCC patients. Lymphocyte transformation assays using larval antigens showed significantly

An immune response to Entamoeba histolytica appears to occur only as a result of tissue invasion by the parasite. Once trophozoites have invaded the intestinal mucosa, a conventional immune response ensues. Skin tests to determine delayed-type hypersensitivity against Entamoeba histolytica antigens have been performed with antigens such as sonicates of

Cellular Immune Response to Flagellin in Man
International Archives of Allergy and Applied Immunology, 2009Cell mediated immunity to flagellin was tested for by delayed hyper-sensitivity (DHS) skin reactions in man, guinea-pig and rabbit, and by production of macrophage migration inhibition factor (MIF) in man. In most humans, there was a cutaneous reaction to intradermal flagellin which was not classical tuberculin type DHS, but was a ‘delayed in time ...

CELLULAR BASIS OF THE IMMUNE RESPONSE
Acta Endocrinologica, 1975ABSTRACT Lymphocytes, the cells competent to initiate immune responses, can be divided into two major groups: thymus-derived or T cells responsible for "cellular immunity" (e. g. delayed hypersensitivity reactions) and bursa (or bursa-equivalent) derived or B cells which produce immunoglobulin (antibody) molecules and are involved in "humoral ...

Regulation of cellular immune responses by selenium
Biological Trace Element Research, 1992Selenium (Se) is an essential nutritional factor that affects the development and expression of cell-mediated immune responses directed toward malignant cells. These studies have shown that dietary (2 ppm for 8 wk) or in in vitro (1 x 10(-7)M) supplementation with Se (as sodium selenite) results in a significant enhancement of the proliferative ...

Cellular Interactions in the Humoral Immune Response
1989Publisher Summary This chapter discusses the interactions between T and B cells and the role of accessory cells and cytokines in the generation of specific antibody responses. The first part of the chapter is a historic perspective followed by a summary of the present-day concepts.
