Abstract:
Environmental pollutants can adversely impact various physiological processes, affecting systems such as the respiratory and immune systems. Immune responses are influenced by various factors including age, hormonal status, genetic background, and notably, sex, with effects extending to both innate and adaptive immunity. External factors, like environmental pollutants, can also disrupt innate and/or adaptive immunity and compromise pathogen recognition and memory against future infections. Furthermore, environmental pollutants can play a pivotal role in the development and exacerbation of many chronic respiratory diseases. It is becoming increasingly evident that environmental pollutants elicit sex-specific effects across different species. This review highlights recent findings on the intricate interplay between sex differences and immune-related effects induced by environmental pollutants, with a particular focus on the dysregulation of pulmonary immune responses.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
