Immunology is the study of the composition, function, and mechanisms of the immune system, as well as the basic immune mechanisms related to diseases. The immune system is the body's defense system against pathogens and foreign substances, protecting health by distinguishing "self" from "non-self."
Lung Cancer, also known as lung carcinoma, is a malignant tumor that originates in the lung tissue. It is typically caused by genetic damage to the DNA of airway cells, often due to smoking or inhalation of harmful chemicals. The damaged airway cells gain the ability to multiply uncontrollably, leading to tumor growth. If left untreated, the tumor can spread throughout the lung, impairing lung function. Eventually, lung tumors can metastasize, spreading to other parts of the body.
Epigenetics is the study of changes in gene function that can be inherited but do not involve alterations to the DNA sequence. At its core, epigenetics investigates the mechanisms that regulate gene expression without changing the underlying DNA sequence. Nuclear signaling refers to signaling pathways within the cell nucleus that are triggered by transcription factors to initiate specific gene expression programs, thereby controlling cellular functions and behaviors.
Developmental biology is the study of the process by which living organisms develop from a single cell (fertilized egg) into mature individuals. It covers the dynamic processes from cell division and differentiation to the formation of tissues, organs, and entire organisms, exploring the mechanisms of embryonic development, cell fate determination, and the principles of morphogenesis. Beyond normal development, it also investigates the mechanisms of developmental abnormalities and related diseases.
Cell markers are molecules or antigens on the cell membrane used to identify specific cells or organelles, and are crucial for cell classification and functional studies. These markers include proteins, glycoproteins, lipids, and carbohydrates, which play key roles in cell recognition, signaling, intercellular communication, and immune responses.
Cell Biology Cell biology is a discipline that studies the structure, function, and mechanisms of cellular activities, and is one of the core fields of modern life sciences. As the basic units of life, cells are studied at multiple levels, ranging from the molecular level to cell populations, with the aim of uncovering how cells maintain vital activities, adapt to environmental changes, and contribute to pathological mechanisms in diseases.
Cardiovascular research is a critical branch of medical science, focusing on the structure, function, and diseases of the heart and blood vessels. The cardiovascular system, which includes the heart, arteries, veins, and capillaries, plays a vital role in delivering oxygen, nutrients, and hormones throughout the body while removing metabolic waste.
Cancer is a disease characterized by abnormal cell proliferation and spread. It originates from genetic mutations in normal cells, which cause the cells to lose control over their growth and division, leading to tumor formation and potential spread to other parts of the body. Cancer is not only a genetic disease but also involves complex interactions between cells and their microenvironment, as well as adaptive evolution driven by natural selection.
Gliomas are tumors that originate from glial cells in the central nervous system (the brain and spinal cord), accounting for approximately 40%-50% of all primary brain tumors. They are also one of the most common and malignant types of tumors in adults' central nervous system. Based on the originating cell type, they can be classified into astrocytomas, ependymomas, or oligodendrogliomas. Due to their infiltrative growth characteristics, they are difficult to treat, have a high recurrence rate, and significantly impact the neurological function and survival period of patients
