  • Effect of hla-dra gene rs8084 variant on development of hiv-1 infection and on expression of interferon-stimulating mx2, ifnm1, adar1 genes

    Russian Journal of Immunology, 2026
    In the subjects infected with HIV, the influence of rs8084 polymorphism suggests that certain alleles may prolong the disease progression at an older age, thus allowing people with specific genotypes to maintain higher CD4 levels even if they are infected later in life. This may indicate a more effective activation of the immune response with age. The present study analyzed the distribution of HIV-1 patients by disease stages depending on age groups, as well as changes in CD4+ per cent levels, and the expression of the MX2, IFNM1, and ADAR1 genes in infected patients. A total of 143 patients diagnosed with HIV-1, aged 14 to 66 years, have been examined. The control group consisted of 67 practically healthy individuals aged 15 to 57 years, who were unrelated, had no clinical signs of HIV infection, and had no hereditary predisposition to the disease. The highest number of infections occurs at the third stage of the disease (symptomatic phase) among young individuals aged 14-35 years. At later stages of the disease, CD4% levels are significantly decreased, indicating the progression of immune deficiency. A correlation was also revealed between the HLA-DRA genotype and CD4% levels, highlighting the potential for a personalized approach to HIV treatment. Moreover, the study revealed a significantly increased expression of the MX2, IFNM1, and ADAR1 genes in HIV-infected patients, thus confirming activation of antiviral mechanisms in response to infection. The study demonstrated that HIV- 1 infection is associated with significant changes in the immune system, as evidenced by a decrease in CD4% levels and an increase in the expression of key antiviral genes such as MX2, IFNM1, and ADAR1. Given the role of genetic factors, such as HLA-DRA polymorphism, in disease progression, the importance of a personalized treatment approach is emphasized.

  • Effect of Unigel Plantum on Lettuce Quality

    Greenhouse farming is an innovative model of agriculture that promotes sustainable production. Advanced greenhouse complexes use hydroponics, which makes it possible to grow vegetables and salads as far north as in Russia’s polar regions and on Sakhalin Island. To improve the yield and quality of lettuce, local farmers need an efficient mineral wool substrate and hydroponics. Biodegradable gels in combination with soil microorganisms are known to stabilize and prolong the effect of organic and mineral complexes.The research featured Aficion green lettuce grown hydroponically in a greenhouse. The control plants were grown in line with the industrial technology, which involved a four-fold weekly foliar treatment with a combination of Ecogel and Agrocen at 0.5 and 0.15%, respectively. The experimental samples were grown on substrate treated with Yunigel Plantum at 0.03 g per pot. The weight of lettuce leaves without roots was determined after cutting; their moisture content was determined after drying to a constant weight. The quality of leaf lettuce was assessed by the content of solids (State Standard GOST 31640-2012), crude protein (GOST 13496.4-2019), and amino acids (M 04-87-2009). The effect of Yunigel Plantum on quality and yield was evaluated by the ripening period, weight, root development, root hair development, moisture content, protein, and amino acids. The study also involved the effect of three different concentrations of humic and fulvic acids (Beres-8) to identify the optimal concentration.Yunigel Plantum_12 increased the yield and growth rate by 20%: as it boosted the root development, the experimental lettuce absorbed nutrients and became rich in essential amino acids. Yunigel Plantum can be recommended for greenhouse lettuce farming since it proved able to increase the yield and improve the nutr itional value of lettuce.

  • Studying the proliferation activity of the plant Сaper (Capparis spinosa L.)

    Plant Science Today, 2024
    The article presents information on the methods and results of studying the influence of extracts prepared from various organs of the caper plant (Capparis spinosa L.), which in the Samarkand region exhibits the absence of proliferative activity of monocyte macrophages and mouse RAW 264.7. There are many scientific and research works devoted to the study of the medicinal properties of Capparis spinose L. cappers growing in Uzbekistan, as well as many works dedicated to identifying the molecular mechanisms of the immunomodulatory properties of the plant, which have not yet been studied. In medicine, consuming ripe fruits of C. spinosa L. has long been known to treat various diseases' inflammatory processes, including stomach inflammation and intestinal bleeding processes of haemorrhoids. The experiments show that concentrations of plant extracts at a concentration of 25.5 ?l have a destructive effect on all samples. A concentration of 1 ?l reduces the proliferative activity of cells of all plant extracts, except for seed extract; as a result, when exposed to 1 ?l of seed extraction, the population level was the highest. In cells stimulated with LPS, the level of proliferation was high at a concentration of 0.5 ?l of extracts of flowers, fruits and roots. Cytotoxicity was observed in extratax leaves, which may explain the antibacterial activity.
