HIV-1 infection does not impair human alveolar macrophage phagocytic function unless combined with cigarette smoking.
OBJECTIVE Macrophages are an important reservoir for the HIV and contribute to innate lung defense by their ability to phagocytose, digest, and process invading pathogens. We hypothesized that HIV-1 infection may lead to a defect in the phagocytic activity of alveolar macrophages. DESIGN In order to test this hypothesis, the phagocytic activity of alveolar macrophages from asymptomatic HIV-1 ...
متن کاملLipids of alveolar macrophages, polymorphonuclear leukocytes, and their phagocytic vesicles.
Phagocytic vesicles were isolated from rabbit alveolar macrophages and guinea pig polymorphonuclear leukocytes that had ingested emulsified paraffin oil. Phospholipids and their fatty acids were determined in whole cells and in the phagocytic vesicle and pellet fractions separated from them. The cholesterol-to-phospholipid ratios in the vesicle fractions were distinctly higher than those of the...
متن کاملCHROMOSOMAL PROTEINS IN PULMONARY ALVEOLAR MACROPHAGES
In this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. Cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. Proteins were then analysed on SDS polyacrylamide gels and densitometric...
متن کاملEffect of bronchoalveolar lavage fluid from Pneumocystis carinii-infected hosts on phagocytic activity of alveolar macrophages.
Alveolar macrophages from Pneumocystis carinii-infected rats are defective in phagocytosis. To investigate whether this defect is due to a certain factor present in P. carinii-infected lungs, alveolar macrophages from uninfected rats were incubated with bronchoalveolar lavage (BAL) fluid samples from P. carinii-infected rats. Alveolar macrophages treated with these BAL fluid samples became defe...
متن کاملCigarette Smoking Decreases Global MicroRNA Expression in Human Alveolar Macrophages
Human alveolar macrophages are critical components of the innate immune system. Cigarette smoking-induced changes in alveolar macrophage gene expression are linked to reduced resistance to pulmonary infections and to the development of emphysema/COPD. We hypothesized that microRNAs (miRNAs) could control, in part, the unique messenger RNA (mRNA) expression profiles found in alveolar macrophages...
