Chemotactic factors in bronchial secretions of cystic fibrosis patients

, 1998
To understand chronic neutrophil attraction into cystic fibrosis airways, both global chemotactic activity and individual chemotactic factors were studied in bronchial secretions. Bronchial secretions of 8 cystic fibrosis patients, collected on the first

Stromal cell-derived factor 1 regulates in vitro sperm migration towards the cumulus-oocyte complex in cattle.

PLoS ONE, 2020
Sperm migration towards an oocyte in the female reproductive tract is an important step for successful fertilization. Although several sperm-chemotactic factors have been identified in mammals, it is unclear whether these chemoattractants contribute to ...

Spontaneous Non‐Catalyzed Molecular Reactions and Interactions in the Human Body: Biomedical Implications

Advanced Science, EarlyView.
ABSTRACT The human body functions as a natural reactor for a vast network of chemical and biological reactions and physical interactions among small molecules, proteins, cells, and numerous other components. These reactions/interactions are essential for maintaining normal physiological functions.

Chemotactic factors in the human follicle at ovulation

, 2000
Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion.

Bronchial epithelial cells release chemotactic activity for lymphocytes

, 1989
Lymphocytes can frequently be observed in association with bronchial tissues. One mechanism that might account for this association is that bronchial epithelial cells might release chemotactic factors for lymphocytes.

Production of cyclooxygenase products and superoxide anion by macrophages in response to chemotactic factors [PDF]

, 1982
Mononuclear phagocytes are knwon to play a key role in various phlogistic reactions by synthesizing and releasing products that may potentiate or inhibit inflammatory processes.

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen
