Оценка полезности гибридного ПЕТ/МР нейроимации во воспламенительной демиэлизации и энцефалите.

В связи с увеличением в последние годы количества гибридных ПЕТ/МСД этот метод все шире используется для нейроимации в клинической практике. Она сочетает преимущества МРТ (включая высокоразрешенную съемку внутрицеребральных повреждений и данных, полученных в результате специализированных последовательности МРТ) с преимуществами ПЕТ, которая визуализирует функциональные изменения в мозге, а также оценивает изменения в количестве миелинов и остроту воспаления. Использование ПЕТ/МОИ может помочь устранить ограничения МРТ, указанные в виде обезображивающих подстрекательских заболеваний (таких, как

Senescent T cells: Beneficial and detrimental roles.

As the thymus involutes during aging, the T-cell pool has to be maintained by the periodic expansion of preexisting T cells during adulthood. A conundrum is that repeated episodes of activation and proliferation drive the differentiation of T cells toward replicative senescence, due to telomere erosion. This review discusses mechanisms that regulate the end-stage differentiation (senescence) of T cells. Although these cells, within both CD4 and CD8 compartments, lose proliferative activity after antigen-specific challenge, they acquire innate-like immune function. While this may confer broad i

Lymph node metastasis in cancer progression: molecular mechanisms, clinical significance and therapeutic interventions.

Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. In recent years

Ascorbic Acid Sensitizes Colorectal Carcinoma to the Cytotoxicity of Arsenic Trioxide via Promoting Reactive Oxygen Species-Dependent Apoptosis and Pyroptosis.

Arsenic trioxide (ATO) is an effective therapeutic agent against acute promyelocytic leukemia (APL); however, its anti-tumor effect on solid tumors such as colorectal cancer (CRC) is still in debate. Ascorbic acid (AA) also produces a selective cytotoxic activity against tumor cells. Here, we exploit the potential benefit of ATO/AA combination in generating cytotoxicity to CRC cells, which may lay the groundwork for the potential combinational chemotherapy of CRCs. According to the results, we found that ATO and AA effectively inhibited the viability of human CRC cells in a synergistic manner.

Targeting the p53 signaling pathway in cancers: Molecular mechanisms and clinical studies.

Tumor suppressor p53 can transcriptionally activate downstream genes in response to stress, and then regulate the cell cycle, DNA repair, metabolism, angiogenesis, apoptosis, and other biological responses. p53 has seven functional domains and 12 splice isoforms, and different domains and subtypes play different roles. The activation and inactivation of p53 are finely regulated and are associated with phosphorylation/acetylation modification and ubiquitination modification, respectively. Abnormal activation of p53 is closely related to the occurrence and development of cancer. While targeted t

Mesenchymal stem cells: A new therapeutic tool for chronic kidney disease.

Chronic kidney disease (CKD) has a major impact on public health, which could progress to end-stage kidney disease (ESRD) and consume many medical resources. Currently, the treatment for CKD has many flaws, so more effective treatment tools are urgently required for CKD. Mesenchymal stem cells (MSCs) are primitive cells with self-renewal and proliferation capacity and differentiation potential. Extensive preclinical and clinical data has shown that cell-based therapies using MSCs can modulate immunity, inhibit inflammatory factors, and improve renal function in CKD, suggesting that MSCs have t

Multiple Myeloma: A Review of the Literature and a Case Report Highlighting the Immunocompromised State of Myeloma Patients.

Multiple myeloma (MM), a malignancy involving plasma cells, disproportionately affects older adults with an average age of diagnosis of about 70 years. Oftentimes, the therapies used in the treatment of MM are associated with a risk for immunotoxicity, lowering the ability of the immune system to fight off opportunistic infections. This is an important relationship for clinicians to realize as the incidence of opportunistic infections in myeloma patients is increasing. As an example, we present a case of a patient with MM who subsequently developed a cryptococcal infection. Our paper will high

Crosstalk of the Wnt/β-Catenin Signaling Pathway in the Induction of Apoptosis on Cancer Cells.

The Wnt/β-catenin signaling pathway plays a major role in cell survival and proliferation, as well as in angiogenesis, migration, invasion, metastasis, and stem cell renewal in various cancer types. However, the modulation (either up- or downregulation) of this pathway can inhibit cell proliferation and apoptosis both through β-catenin-dependent and independent mechanisms, and by crosstalk with other signaling pathways in a wide range of malignant tumors. Existing studies have reported conflicting results, indicating that the Wnt signaling can have both oncogenic and tumor-suppressing roles, d

Многофункциональная роль аполипопротеина Е в нейродегенеративных заболеваниях.

Генетическое разнообразие в гене аполипопротеина Е (АпоЭ) было определено в качестве основного фактора риска уязвимости в плане генетического риска для спорадического заболевания Альцгеймера (САД). В частности, аллея АпоЕ4 является важным фактором риска для SAD, в то время как аллея АпоЕ2 обеспечивает защиту по сравнению с более распространенными аллеями АпоЕ3. В настоящем обзоре рассматривается роль АпоЭ в АД и других нейродегенеративных расстройствах. ApoE — белок переноса холестерина — влияет на несколько путей нейродегенерации, особенно в AD. Помимо своей установленной роли в метаболизме и

ATG5 контролирует выражение CD80 в клетках B и фигурах, соединяющих CD4+T реакции клеток.

Макроаутофагичная/аутофагическая техника была задействована в поддержке MHC класса II, но скомпрометировала MHC класса I, ограничивая представление антигена дендритическими элементами (DCs). Здесь мы сообщаем, что потеря основного аутофагического белка ATG5 в клетках B уменьшает интернализацию и стабилизирует совместное выражение поверхности CD80. В модели мыши без аутоиммунного энцефаломиелита (EAE) совместная передача индуктивных микробных клеток B (iGB) в ATG5 с клетками CD4+T, характерными для MOG, ускоренное развитие заболеваний. Блокада CD80 отменила усиленные ответные реакции CD4+T-клет

Resveratrol Nanoformulations for Cancer Management: A Comprehensive Review of Disease-Specific Strategies and Clinical Translational Barriers.

Cancer remains a leading cause of mortality worldwide, highlighting the need for therapeutic strategies that reduce systemic toxicity and drug resistance. Resveratrol (RES), a natural polyphenolic stilbenoid, possesses antioxidant, anti-inflammatory, pro-apoptotic, anti-metastatic, and chemosensitizing activities. However, its clinical translation is limited by poor aqueous solubility, chemical instability, rapid metabolic clearance, and consequently low systemic bioavailability. Nanotechnology-based drug delivery systems provide a promising strategy to address these limitations. This review s

Unraveling the Anticancer Effect of Curcumin and Resveratrol.

Resveratrol and curcumin are natural products with important therapeutic properties useful to treat several human diseases, including cancer. In the last years, the number of studies describing the effect of both polyphenols against cancer has increased; however, the mechanism of action in all of those cases is not completely comprehended. The unspecific effect and the ability to interfere in assays by both polyphenols make this challenge even more difficult. Herein, we analyzed the anticancer activity of resveratrol and curcumin reported in the literature in the last 11 years, in order to unr

The trinity of T cell engagement: navigating the molecular and clinical landscape of CAR-T, TILs, and TCEs in the war against cancer.

The advent of cancer immunotherapy has fundamentally restructured the oncological paradigm, moving away from agents that directly target tumor cell kinetics toward strategies that empower the host immune system to recognize and eliminate malignancy. Central to this revolution is the cytotoxic T lymphocyte (CTL), now harnessed as a potent "living drug" through engineered and naturally selected modalities. This review provides a critical, in-depth examination of the three dominant pillars of T cell-driven therapies: Chimeric Antigen Receptor T-cell (CAR-T) therapy, Tumor-Infiltrating Lymphocyte

Redox Remodeling by Nutraceuticals for Prevention and Treatment of Acute and Chronic Inflammation.

Antioxidant-rich dietary regimens are considered the best practice to maintain health, control inflammation, and prevent inflammatory diseases. Yet, nutraceuticals as food supplements are self-prescribed and purchasable over the counter by healthy individuals for the purpose of beneficial effects on fitness and aging. Hence, the effectiveness, safety, and correct intake of these compounds need to be better explored. Since redox-modulating activity of these compounds appears to be involved in activation and or suppression of immune cells, the preventive use of nutraceuticals is very attractive
