  • Background: Bronchiectasis is a chronic respiratory condition leading to recurrent respiratory infections. Despite the use of antibiotics and other standard treatments, managing bronchiectasis remains challenging due to the frequent recurrence of airway infections and concerns about antimicrobial resistance. Given these challenges, traditional Korean medicine (TKM) has gained attention due to its potential to reduce the frequency of respiratory infections, possibly minimizing the need for antibiotics. Case report: A 59-year-old female with bronchiectasis experienced recurrent pneumonia and was treated with antibiotics for over 2 weeks without any significant improvement in clinical symptoms. She received comprehensive Korean medicine treatment, including herbal medicine (Sikyungbanha-tang combined with Bigwabojungikki-tang-gami), acupuncture, and Chuna manual therapy, for pulmonary rehabilitation. Post-treatment, clinically meaningful improvements were observed in symptoms, serum C-reactive protein (CRP) levels, and bronchopneumonic lesions on chest X-rays. Conclusion: This case suggests that complex traditional Korean medicine treatments for recurrent chronic airway inflammation due to bronchiectasis can lead to clinically significant improvements in symptoms and help to prevent recurrence.

  • Background: Asthma and chronic obstructive pulmonary disease (COPD) both require long-term management, and patients with asthma-COPD overlap (ACO) need comprehensive and prolonged care beyond pharmacotherapy. However, due to limited research on ACO, treatment strategies and long-term outcomes remain unclear. This highlights the need for further multidisciplinary research to improve ACO treatment and prognosis. Case Presentation: This case report describes a patient who presented with symptoms of cough, sputum, wheezing, dyspnea, and oral dryness. The patient was diagnosed with ACO and received a combination of Korean medicine treatments alongside standard asthma medication for 15 days. Standardized tools were used to evaluate symptoms and quality of life, respectively. After treatment, Medical Research Council scale, Leicester cough questionnaire Korean-Version and Numerical Rating Score demonstrated clinically meaningful improvement, and Total IgE and Eosinophils were slightly decreased. Conclusion: This case suggests Korean medicine treatments might be effective in managing symptoms in patients with ACO and enhancing quality of life.

  • In this paper the structure of 2-DOF controller based on artificial immune network algorithms has been suggested for nonlinear system. Up to present time, a number of structures of the 2-DOF controllers are considered as 2-DOF (2-Degrees Of Freedom) control functions. However, a general view is provided that they are the special cases of either the state feedback or the modification of PID controllers. On the other hand, the immune network system possesses a self organizing and distributed memory, also it has an adaptive function by feed back law to its external environment and allows a PDP (parallel distributed processing) network to complete patterns against the environmental situation, since antibody recognizes specific antigens which are the foreign substances that invade living creatures. Therefore, it can provide optimal solution to external environment. Simulation results by immune based 2-DOF controller reveal that immune algorithm is an effective approach to search for 2-DOF controller.

  • The effects of panaxytrion as known to be a cytotoxic substance isolated from Panax ginseng on the immune responses were examined. The i.p. administration of panaxytriol to normal mice for 6 consecutive days as doses of 5, 10 and 20 mg/kg suppressed the increase of body weight dose-dependently but did not affect the weight ratio of immunoorgans to body weight, No significant changes were observed in the humoral immune responses as measured by Arthus reaction and plaque forming cells and in the cellular immune response as measured by delayed hypersensitivity as well as phagocytic activity of reticuloendotherial system. These results suggested that panaxytriol, a cytotoxic substance to cancer cells, has no detrimental effects on the immune function in normal mice.

  • Recently pathotoxicological study of lymphoid organs by administration of some phthalate ester in rats, indicated marked effect of architechure of thymus, spleen, and lymphonodes. Dioctyl phthalate (DOP), one of the phthalate ester, caused statistically significant reduction in the weights of various lymphoid organs. This senstivity of the lymphoid organ to phthalate toxicity which could lead to adverse effects on the immune response and also suppression of immune system. Therfore it is possible the presense of di-(2-ethylhexyl) phthalate (DEHP), one of the phthalate ester as well as DOP, in spleen and other organs might have some moderately effect on the function of the immune system, So our present study was proceeded to assess the effect of DEHP on the immunotoxicity in mouse. In the immune response of DEHP administered mice, HA, HY, Arthus reaction and Rosette forming cell were decreased but DTH was increased. Furthermore, in the DEHP plus ethanol group, HA, HY, Arthus reaction and Rosette forming cell were remarkably decreased and elevation of DTH was inhibited.

  • NF-${\kappa}B$/Rel transcription factor family participates in diverse biological processes including embryo development, hematopoiesis, immune regulation, as well as neuronal functions. In this review, the NF-${\kappa}B$/Rel signal transduction pathways and their important roles in the regulation of immune system will be discussed. NF-${\kappa}B$/Rel members execute distinct functions in multiple immune cell types via the regulation of target genes essential for cell proliferation, survival, effector functions, cell trafficking and communication, as well as the formation of lymphoid architecture. Consequently, proper activation of NF-${\kappa}B$/Rel during immune responses to allergens, auto-antigens, allo-antigens, and pathogenic infection is crucial for the integrity of host innate and adaptive immunity.

  • To elucidate new biological ingredients in cold-brew coffee extracted with cold water, crude polysaccharide (CCP-0) was isolated by ethanol precipitation, and its immune-stimulating activities were assayed. CCP-0 mainly comprised galactose (53.6%), mannose (15.7%), arabinose (11.9%), and uronic acid (12.4%), suggesting that it might exist as a mixture of galactomannan and arabinogalactan. CCP-0 significantly increased cell proliferation on both murine peritoneal macrophages and splenocytes in a dose dependent manner. CCP-0 also significantly augmented nitric oxide and reactive oxygen species production by murine peritoneal macrophages. In addition, macrophages stimulated by CCP-0 enhanced production of various cytokines such as tumor necrosis factor-${\alpha}$, interleukin (IL)-6, and IL-12. In an in vitro assay for intestinal immune-modulating activity, CCP-0 showed higher bone-marrow cell-proliferation activity through Peyer's patch cells at $100{\mu}g/mL$ than the negative control. These results suggest that CCP-0 may potentially enhance macrophage functions and the intestinal immune system.

  • Dendritic cells (DCs) are professional antigen-presenting cells (APCs) that bridge innate and adaptive immune responses, thereby leading to immune activation. DCs have been known to recognize pathogen-associated molecular patterns such as lipopolysaccharides (LPS) and nucleic acids via their pattern recognition receptors, which trigger signaling of their maturation and effector functions. Furthermore, DCs take up and process antigens as a form of peptide loaded on the major histocompatibility complex (MHC) and present them to T cells, which are responsible for the adaptive immune response. Conversely, DCs can also play a role in inducing immune suppression under specific circumstances. From this perspective, the role of DCs is related to tolerance rather than immunity. Immunologists refer to these special DCs as tolerogenic DCs (tolDCs). However, the definition of tolDCs is controversial, and there is limited information on their development and characteristics. In this review, we discuss the current concept of tolDCs, cutting-edge methods for generating tolDCs in vitro, and future applications of tolDCs, including clinical use.

  • Neutrophils, the most abundant innate immune cells, play essential roles in the innate immune system. As key innate immune cells, neutrophils detect intrusion of pathogens and initiate immune cascades with their functions; swarming (arresting), cytokine production, degranulation, phagocytosis, and projection of neutrophil extracellular trap. Because of their short lifespan and consumption during immune response, neutrophils need to be generated consistently, and generation of newborn neutrophils (granulopoiesis) should fulfill the environmental/systemic demands for training in cases of infection. Accumulating evidence suggests that neutrophils also play important roles in the regulation of adaptive immunity. Neutrophil-mediated immune responses end with apoptosis of the cells, and proper phagocytosis of the apoptotic body (efferocytosis) is crucial for initial and post resolution by producing tolerogenic innate/adaptive immune cells. However, inflammatory cues can impair these cascades, resulting in systemic immune activation; necrotic/pyroptotic neutrophil bodies can aggravate the excessive inflammation, increasing inflammatory macrophage and dendritic cell activation and subsequent TH1/TH17 responses contributing to the regulation of the pathogenesis of autoimmune disease. In this review, we briefly introduce recent studies of neutrophil function as players of immune response.
