Description

The fast-growing field of white blood cell trafficking has created new and exciting opportunities for clinics. Trafficking signals are defined that precisely control the movement of specific subsets of immune cells that enter and leave specific tissues. Because the accumulation of leukocytes in tissues contributes to a variety of diseases, these molecular codes have provided new targets for inhibiting clinically validated tissue-specific inflammation. However, the migration of immune cells is also important for providing the tissue with a protective immune response. Therefore, the challenge for the future is to identify the transporter molecules that most specifically inhibit the major subset of cells that promote the disease process without affecting the migration and function of leukocytes required for defensive immunity.

Various studies of the role of homeostasis and immune regulatory mechanisms in health and disease, and their important potential as targets in clinical applications [1]. Aerostatic stress and loss of immune homeostasis can exacerbate tissue damage and impair tissue repair during tissue damage. A better understanding of the molecules that regulate immune processes may lead to the development of innovative therapies in the future. Trafficking in white blood cells is an important process that enables and regulates the role of immune surveillance. In fact, the high mobility of immune cells is associated with their ability to recognize and eliminate pathogens and tumors [2]. These mobility abilities are also associated with the development of unwanted reactions to autologous or transplanted tissue.

Organism-wide transport and local motility within tissues have a direct impact on lymphocyte ontogeny and function, including effector and regulatory T cell maturation and differentiation [3]. Ultimately, the regulation of T cell migration activity leads to a coordinated antigen scan of T cells on their way from the blood to lymphoid organs and peripheral non-lymphoid tissues. Despite a better understanding of the molecular and cellular basis of the complex processes of T cell migration, the mechanistic rules governing migration patterns at various stages of T cell development and activation are described in detail. In addition, new imaging technologies regulate the motility underlying T cell shape remodeling, the initial interaction with antigen-carrying cells, and the final decisions that affect the effector immune response or its regulation [4].

Immune cell migration is essential for almost every step of surveillance. The ability to monitor immune cells requires both long-range patrols throughout the body and local scans of molecular cues within cells and tissues. Immune cells travel long distances using the circulation of blood and lymph throughout the body. Importantly, immune cells in the circulatory system also ensure vascular integrity, but little is known about how they can detect abnormalities and restore homeostasis. Creeping monocytes in blood vessels switch from random movement to the motility when damaged endothelium is detected. This mode of exercise improves local patrol by alternating fast and directional, slow and random stages of movement [5]. Interestingly, this type of mobility has previously been described as an optimal search strategy for T cells in infected brains. The adaptation of migration behavior to local situations in both health and illness is a common feature of immune cells. The transport of monocytes and macrophages into the arteries, as well as their contribution to the return to homeostasis, changes during atherosclerosis, emphasizing the dual role of macrophages in both plaque establishment and regression. Elucidating the molecular mechanisms that link immune cell migration to the development of disease may help facilitate new therapeutic strategies. To leave the systemic circulation, immune cells must first recognize the exit signal, then attach, roll, and move from the circulation to the tissue stromal. These processes are known to depend on integrin activation and conformational changes, but it is not yet fully understood how integrin activation is finetuned. After migration, immune cells crawl under the endothelium before entering the stromal tissue.
