Damage Mechanism of CK2 and IKAROS in Philadelphia Like Acute Lymphoblastic Leukemia

引用

Journal of Biosciences and Medicines 2024年第4期12卷 49-59页

作者： Ignacio Vélez-Rodríguez Victoria carranza-Aranda Facultad Mexicana de Medicina Universidad La Salle Tlalpan M&#233xico Hospital General de Mé xico Cuauht&#233moc M&#233xico

Acute lymphoblastic leukemia (ALL) is characterized by immature and poorly differentiated B lymphocytes in large numbers in the blood. B cells are distinct from the cell types involved in their development (common lymphoid progenitor cells, pro-B cells, pre-B cells, and mature cells). The process of B cell maturation depends on precise communication within the cell: signals activate specific genes that are essential for proper development. Errors in this intricate signaling network can lead to issues with B cell function and contribute to disease. B-lineage acute lymphoid leukemias, malignancies of precursor-stage B lymphoid cells inhibit lymphoid differentiation, leading to abnormal cell proliferation and survival. The process of developing leukemia (leukemogenesis) can be triggered by an overproduction of both hematopoietic stem cells (the cells that form all blood cells) and the immature versions of white blood cells called lymphoblasts. Acute lymphoblastic leukemia (ALL) with the presence of the Philadelphia chromosome (ALL Ph) is classified as a high-risk manifestation of the disease, this chromosome is the product of the reciprocal translocation, whose product is a BCR-ABL fusion protein. It is a highly active tyrosine kinase that can transform hematopoietic cells into cytokine-independent. Hyperphosphorylation cascades inhibit the differentiating function of IKZF1 as a tumor suppressor gene which leads to an abnormal proliferation of B cells due to the presence of the Philadelphia chromosome;it inhibits the differentiating process, leukemogenesis involving immature B cells in the bloodstream can result from the uncontrolled growth and division of hematopoietic stem cells and immature lymphoblasts (the precursors to B cells).

Fungi Associated with Sand and Plants from Marine Coastlines: Potential Relevance for Human Health

引用

Advances in Microbiology 2024年第6期14卷 303-316页

作者： Marina carrasco-Acosta Pilar Garcia-Jimenez Department of Biology Universidad de Las Palmas de Gran Canaria Campus de Tafira Las Palmas Spain

The fungal community associated with beach sand and plants located along marine coasts are an under-studied area of research despite its potential relevance to human health. In this study, we isolated and identified the cultivable mycobiota associated with sand and plants collected along the coast of Gran Canaria (Spain) using culture-dependent and -independent methods. Clinically relevant species belonging to Cryptococcus spp. and related genera such as Naganishia and Papilotrema were isolated and identified from shoreline plants. Moreover, Candida tropicalis was isolated from beach sand, and Aspergillus fumigatus and Aspergillus terreus strains were associated with both types of samples (i.e., plants and beach sand). We conclude that beach sand and shoreline plants are potential reservoirs of fungi of high clinical interest. We recommend including beach sand and plants from the environment when assessing the quality of marine coastal systems. Our results open a framework for studying the natural marine environment and its role in the epidemiology of infectious diseases in order to more accurately manage public health.

Etiological Agent, Pathogenesis, Diagnosis, Treatment, Measures for Prevention and Control of Caseous Lymphadenitis Disease in the Small Ruminants with Special Reference to Sheep

Journal of Biosciences and Medicines 2024年第5期12卷 154-170页

Caseous lymphadenitis (CL) is a chronic infectious disease caused by Corynebacterium pseudotuberculosis (C. pseudotuberculosis) that is transmitted mainly by contact with contaminated exudate wounds. Caseous lymphadenitis affects different species of animals and is considered an occupational zoonotic disease. CL is responsible for important economic losses in the small ruminant industry, which include decreased production, damaged quality of milk and wool, reproductive disorders, total or partial confiscation of carcasses, and depreciation of the skin. Caseous lymphadenitis disease can present in two clinical pictures: a skin or superficial picture and a visceral or deep picture. The presumptive diagnosis of CL in the skin is based on the exploration of superficial lymph nodes. These have little value in diagnosing visceral CL, where the main sign is emaciation. The prevention and control of CL involve identifying the skin condition and debriding the abscesses. In addition to the treatment of superficial lesions, the animal facilities must be repaired and adapted. To avoid exposure of negative herds to CL, new animals must be subjected to observation to identify any of the clinical manifestations. Another form of control is vaccination, though only some countries have commercial vaccines. General information on the etiological agent and its characteristics can be used to improve the understanding of this disease.

PIEZO2是由背根神经节(dorsal root ganglion,DRG)中大多数感觉神经元表达的一种三聚体机械门控离子通道。在遗传学层面上,机械敏感的PIEZO2通道是小鼠和人类产生正常触觉所必需的。PIEZO2通道受膜电压调节,只有在去极化的膜电压下,所有通道才能被机械力打开;而在正常负的静息膜电位下,大多数PIEZO2通道受到电压的阻滞。然而,PIEZO2通道这种不寻常的生物物理特性的生理功能尚不清楚。该研究通过基因敲入构建Piezo2基因特定突变的小鼠模型,揭示体内改变PIEZO2电压敏感性所产生的生理影响。本文作者检测了从DRG分离的感觉神经元中的内源性机械敏感电流,使用电生理技术表征了机械感受器和伤害感受器的功能,并且对小鼠进行行为和形态学评估。研究结果发现,PIEZO2通道中进化保守的精氨酸(R2756)位点的突变减轻了电压阻滞,降低了通道激活的机械阈值。R2756位点突变导致伤害感受器的机械敏感电流显著增强,而其他机械感受器仅受轻微影响。行为学上,Piezo2点突变敲入小鼠展现出对伤害性机械刺激的超敏反应。该研究指出在人类慢性疼痛综合征中出现的伤害感受器的持续激活和敏化可能与PIEZO2离子通道电压阻滞的减轻有关。
