SLAM and CD31: signaling molecules involved in cytokine secretion during the development of innate and adaptive immune responses
Immune cells are modulated through the crosslinking of receptors named “immunoreceptors”. Ligation of immunoreceptors by their ligands induces a tyrosine-phosphorylation signal that is essential for cell activation or ...
Targeted inhibition of galectin-1 gene expression in tumor cells results in heightened T cell-mediated rejection: a potential mechanism of tumor-immune privilege
(Cell Press, 2004-03)
Despite the existence of tumor-specific immune cells, most tumors have devised strategies to avoid immune attack. We demonstrate here that galectin-1 (Gal-1), a negative regulator of T cell activation and survival, plays ...
Anandamide prior to sensitization increases cell-mediated immunity in mice
(ELSEVIER SCIENCE BV, 2010)
The endocannabinoid system has become a topic of great interest in pharmacology due to its remarkable distribution in mammal organisms and capacity to play a modulatory role on several physiological systems, including ...
Mind the gaps in tumor immunity: impact of connexin mediated intercellular connections
(Frontiers media SA, 2017)
Gap junctions (GJs)-mediated intercellular communications (GJICs) are connexin (Cx)-formed plasma membrane channels that allow for the passage of small molecules between adjacent cells, and are involved in several ...
Immunology of onchocerciasis. II. Modulatory effects of serum and cell factors on lymphocyte proliferative responses to mitogens and alloantigens
(Revista Doyma de Inmunología, 2017)
Effects of antihelminthic treatment on cell-mediated immunity in Gentoo penguin chicks
Intestinal parasites suppose a cost to hosts as they compete directly for nutritional resources. Therefore, hosts must defend themselves against intestinal parasites by mounting an immune response. Many penguin species ...
Cellular Immunity in Current Active Pulmonary Tuberculosis
(The American review of respiratory disease, 2017)
Experimental infection of Leishmania chagasi in immunosuppressed balb/c mice: cellular immune response and parasite burden
(Universidade Estadual Paulista (UNESP), Centro de Estudos de Venenos e Animais Peçonhentos (CEVAP), 2008-01-01)
The immune response to leishmaniasis can result in a polarization of a subpopulation of T lymphocytes, which leads to a different cell phenotype and results in immune protection or exacerbation of the disease. Leishmanias ...
Cell mediated immune response in canine antirabies vaccination
(Instituto de Medicina Tropical, 1985-02-01)
The Authors studied the cell mediated immunity (CMI) and humoral antibody levels raised in response to canine antirabies vaccination and revaccination. The vaccine used was the FUENZALIDA & PALACIOS which is routinelly ...
