Humanized antibodies vary and have certain effects, but they are expensive and require repeated administration. We developed cells which constantly express a humanized antibody, and we performed anticancer humanized antibody therapy involving cell transplantation. Genes with the same amino acid sequence as that of the variable region of trastuzumab (Herceptin) as the humanized anti-HER2 monoclo...
Natural killer(NK) cells are defined as effector cells that have the capacity of spontaneous cytotoxicity toward various target cells and are not major histocompatibility complex(MHC) restricted. NK cells are the first line of immune system defence and serve in surveillance of certain tumor and virus-infected cells. The aim of this study was to determine CD16++CD56+ marker(NK cells) in h...
The putative factors that couple the signal transduction from surface receptors to the activation of cytokine synthesis in natural killer (NK) cells have not been elucidated. We report here that the nuclear factor of activated T cells (NFATp), a cyclosporin A (CsA)-sensitive factor that regulates the transcription of several cytokines, mediates CD16-induced activation of cytokine genes in human...
BACKGROUND Monocytes play a central role in HIV neuropathogenesis, but there are limited data on monocyte subsets and markers of monocyte activation in perinatally HIV-infected children. OBJECTIVE To determine the relationship between monocyte subsets, the sCD163 monocyte activation marker, and neuropsychological performance among perinatally HIV-infected children initiating antiretroviral th...
Our aim was to define the distribution of monocyte subsets in a cohort of congestive heart failure (CHF) patients, to verify whether increased severity of CHF is linked to the expansion of specific monocyte subsets, and finally to investigate the relationship between monocyte subset relative frequencies, laboratory parameters of inflammation, and monocyte ACE expression. Thirty consecutive CHF ...
Dermatomyositis (DM) is a chronic, systemic autoimmune disease affecting the skin, muscle, and lungs. Lenabasum, non-psychoactive cannabinoid type 2 receptor (CB2R) agonist, currently being investigated as non-immunosuppressive treatment option for DM. The activation of CB2R has been shown to reduce several key pro-inflammatory cytokines implicated in Our lab previously demonstrated via immunoh...
Background: Human peripheral blood NK cells constitutively express CD56 and CD16 antigens. Peripheral blood NK cells seem to be strongly related with decidual NK cells, and may reflect the decidual NK cell functional status. There are varied reports concerning the relationship between NK cell cytotoxicity in women with recurrent spontaneous abortion. Objective: To study NK activity in women wit...
Background and purpose: Circulating monocytes are divided into different subpopulations according to the expression of CD14 and CD16. In this study, we investigated the correlation between the severity of coronary artery disease (CAD) and the frequency of two monocyte subsets and also expression level of CCR1 receptor on these monocytes. Materials and methods: The study was conducted in 88 p...
