the physiologic function of the immune system is defense against infectious microbes and internal tumour cells, therefore, need to have precise modulatory mechanisms to maintain the body homeostasis. the mammalian cellular cd200 (ox2)/cd200r interaction is one of such modulatory mechanisms in which myeloid and lymphoid cells are regulated. cd200 and cd200r molecules are membrane proteins that t...
The hybridization of artificial immune system with cellular automata (CA-AIS) is a novel method. In this hybrid model, the cellular automaton within each cell deploys the artificial immune system algorithm under optimization context in order to increase its fitness by using its neighbor’s efforts. The hybrid model CA-AIS is introduced to fix the standard artificial immune system’s weaknesses. T...
mesenchymal stem cells (mscs),as the major stem cells for cell therapy, have been studied from different aspects in pre-clinical and clinical settings for more than a decade. these cells modulate the immune system (humoral and cellular immune responses) in vitro by producing soluble factors (anti-inflammatory molecules) and/or making cell-cell contacts. hence they could be used in regenerative ...
Recent studies in single cell RNA sequencing have improved understanding of the structure immune subpopulation atherosclerosis. With help novel technologies, new subpopulations cells involved atherosclerosis been identified. In addition, a following relatively common and strong cardiovascular risk factor has emerged: clonal hematopoiesis indeterminate potential resulting from accumulation somat...
Background: Development of an effective vaccine is highly needed in order to restrict the AIDS pandemic. DNA vaccines initiate both arms of immunity without the potential of causing disease. HIV-1 p24 and gp41 (gag and env) proteins play important roles in viral pathogenesis and are effective candidates for immune induction and vaccine design. Objective: In this study, new DNA vaccine candidate...
The plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. During the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ROS signaling, hormone activation and gene expression reprogramming. In plants, microRNAs (miRNAs) are key post-transcript...
Background and purpose: Ïn recent years, different studies have been performed regarding the influence of magnetic field on the immune system. There are many contraversies about the effects of different frequencies and amplitudes on the immune system. Materials and methods : Ïn this experimental study, the effects of different frequencies of magnetic field (0,5,50,500 and 5000 Hz) have bee...
comparison of fumaric acid 5% cream versus triamcinolone 0.1% cream in the treatment of hand eczema.
hand eczema is a common distressing skin problem. it is an immune reaction to haptens. thus, substances that inhibit immune system can be effective in the treatment of hand eczema. in this study, topical fumaric acid 5% cream is compared with topical steroid in the treatment of hand eczema. patients with hand eczema were randomly divided into two groups. one group received fumaric acid 5% in a ...
