Effects of CD18 Deficiency on the Emigration

Effects of CD18 deficiency on the emigration of murine neutrophils during pneumonia.

We hypothesized that CD18 deficiency would impair the ability of neutrophils to emigrate from pulmonary blood vessels during certain pneumonias. To directly compare the abilities of wild-type (WT) and CD18-deficient neutrophils to emigrate, mice with both types of leukocytes in their blood were generated by reconstituting the hemopoietic systems of lethally irradiated C57BL/6 mice with mixtures...

Murine Neutrophils During Pneumonia Effects of CD18 Deficiency on the Emigration

Neutrophil Emigration in the Skin, Lungs, and Peritoneum: Different Requirements for CD11/CD18 Revealed by CD18-deficient Mice

To determine the role of CD11/CD18 complexes in neutrophil emigration, inflammation was induced in the skin, lungs, or peritoneum of mutant mice deficient in CD18 (CD18-/- mutants). Peripheral blood of CD18-/- mutants contained 11-fold more neutrophils than did blood of wild-type (WT) mice. During irritant dermatitis induced by topical application of croton oil, the number of emigrated neutroph...

Combinatorial requirements for adhesion molecules in mediating neutrophil emigration during bacterial peritonitis in mice.

To investigate the requirements for adhesion molecules in neutrophil emigration during peritonitis, mice received intraperitoneal injections of Streptococcus pneumoniae while the functions of multiple adhesion molecules were blocked. Emigration after 4 h was compromised by antibodies against ICAM-1 or genetic deficiency of ICAM-1. Anti-CD11a/CD18 antibodies decreased emigration in ICAM-1 mutant...

Detection of New Silent Mutation at 348 bp Position in a CD18 Gene in Holstein Cattle Normal and Heterozygous for Bovine Leukocyte Adhesion Deficiency Syndrome

In India, Holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. Blood samples are collected in ethylenediaminetetraacetic acid (EDTA) coated tubes and DNA was isolated by using phenol-chloroform method. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) wereperformed by using...
