The Role of Gamma Delta T Lymphocytes in Physiological and Pathological Condition-Focus on Psoriasis, Atopic Dermatitis, Autoimmune Disorders, Cancer and Lymphomas.

Gamma delta (γδ) T cells are a heterogeneous population of cells that play roles in inflammation, host tissue repair, clearance of viral and bacterial pathogens, regulation of immune processes, and tumor surveillance. Recent research suggests that these are the main skin cells that produce interleukin-17 (I-17). Furthermore, γδ T cells exhibit memory-cell-like characteristics that mediate repeated episodes of psoriatic inflammation. γδ T cells are found in epithelial tissues, where many cancers develop. There, they participate in antitumor immunity as cytotoxic cells or as immune coordinators.

Ageing, autoimmunity and arthritis: senescence of the B cell compartment - implications for humoral immunity.

Immunosenescence is associated with a decline in both T and B lymphocyte function. Although aged individuals have normal numbers of B cells in the periphery and are capable of mounting robust humoral responses, the antibodies produced are generally of lower affinity and are less protective than those produced by young animals. Here we review multiple studies that address the mechanisms that contribute to this decline. Taken together, these studies suggest that age-associated loss of the ability to generate protective humoral immunity results in part from reduced B lymphopoiesis. As the output

Overview of Dual-Acting Drug Methotrexate in Different Neurological Diseases, Autoimmune Pathologies and Cancers.

Methotrexate, a structural analogue of folic acid, is one of the most effective and extensively used drugs for treating many kinds of cancer or severe and resistant forms of autoimmune diseases. In this paper, we take an overview of the present state of knowledge with regards to complex mechanisms of methotrexate action and its applications as immunosuppressive drug or chemotherapeutic agent in oncological combination therapy. In addition, the issue of the potential benefits of methotrexate in the development of neurological disorders in Alzheimer's disease or myasthenia gravis will be discuss

Inflammatory Microenvironment and Specific T Cells in Myeloproliferative Neoplasms: Immunopathogenesis and Novel Immunotherapies.

The Philadelphia-negative myeloproliferative neoplasms (MPNs) are malignancies of the hematopoietic stem cell (HSC) arising as a consequence of clonal proliferation driven by somatically acquired driver mutations in discrete genes (JAK2, CALR, MPL). In recent years, along with the advances in molecular characterization, the role of immune dysregulation has been achieving increasing relevance in the pathogenesis and evolution of MPNs. In particular, a growing number of studies have shown that MPNs are often associated with detrimental cytokine milieu, expansion of the monocyte/macrophage compar

Blastic Plasmacytoid Dendritic Cell Neoplasm: A Case Report.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an uncommon hematological tumor originating from the precursor of plasmacytoid dendritic cells (pDCs) with a persistent and progressive course of illness. Despite being an aggressive disease BPDCN has an initial indolent course manifested as skin lesions. Alongside or following the skin lesion, the extra-cutaneous manifestation develops and includes lymphadenopathy, splenomegaly, and hepatomegaly. The BPDCN diagnosis is mainly based on the immunophenotype.  Herein, we report the case of a 72-year-old male patient who presented with a hist

Canine Multicentric Lymphoma: Diagnostic, Treatment, and Prognostic Insights.

Lymphoma accounts for 24% of all documented canine neoplasms and 85% of hematological malignancies, while multicentric lymphoma corresponds to 84% of all canine lymphomas. Canine lymphomas of B-cell origin account for 60% to 80% of lymphomas. Similar to humans, the histologic grade, architecture, as well as immunophenotype determination, are crucial. These lesions are the most prevalent spontaneous tumors in dogs and this species may be a valuable animal model for the study of human non-Hodgkin's lymphoma. Therefore, it is important to investigate and assess therapeutic responses and to seek p

Сопутствующая реанимация острого миелоида лейкемии, связанного с терапией, и ИгГ-МГС во время устного децитабина-седазуридина: доклад по делу.

Фон и клиническая значимость: связь между острой миэлоидной лейкемией (АМЛ) и моноклонной гаммопатией неопределенного значения (МГУС) является редкой и, вероятно, случайной из-за аналогичной эпидемиологии этих двух кровеносных расстройств у пожилых пациентов, которые не имеют права на интенсивную химиотерапию или агрессивное лечение, поскольку они могут быть чрезмерно миэлоспрессивными. Такие методы лечения включают в себя те, которые содержат венетоклакс, легкую для использования разнородную форму децитабина-цедазуридина (DEC-C), которая в настоящее время доступна и утверждена для целей борьб

Selective inhibitors of nuclear export (SINE) in hematological malignancies.

Regulated nucleo-cytoplasmic transport plays a major role in maintaining cellular homeostasis. CRM1 (chromosome region maintenance 1 or exportin 1 or XPO 1) is responsible for the nucleo-cytoplasmic transport of more than 200 proteins, including most of the tumor suppressor proteins (TSP). CRM1 is overexpressed in pancreatic cancer, osteosarcoma, glioma, cervical and hematological malignancies. This inspired the development of novel agents that selectively inhibit nuclear exportins (SINEs). In this review we focus on the significance of CRM1 in carcinogenesis and review the new development of

Риск синхронных и вторых первичных недугов у поддающихся трансплантации пациентов с множественным миэломой, обработанных линалидомидом.

Согласно сообщениям, повышенный риск возникновения вторых первичных магнентов (СМП) для лиц, имеющих право на трансплантацию (ТИ), с недавно поставленным диагнозом множественной миеломы (НДММ), подвергающихся воздействию линалидомида (Лен), при том понимании, что Лен часто соприкасался с алкилирующими агентами и что исследования не исключали синхронных маньянов (СИМ). Мы поставили перед собой цель оценить соответствующий СИМ в отношении рисков, связанных с СМП у пациентов ТИ, которые лечили с Леном как прифронтовой терапией. Мы провели исследование на основе регистрации раковых заболеваний с в

Engaging natural killer cells for cancer therapy via NKG2D, CD16A and other receptors.

The field of immuno-oncology has revolutionized cancer patient care and improved survival and quality of life for patients. Much of the focus in the field has been on exploiting the power of the adaptive immune response through therapeutic targeting of T cells. While these approaches have markedly advanced the field, some challenges remain, and the clinical benefit of T cell therapies does not extend to all patients or tumor indications. Alternative strategies, such as engaging the innate immune system, have become an intense area of focus in the field. In particular, the engagement of natural
