Hyphal Als proteins act as CR3 ligands to promote immune responses against Candida albicans.

Patients with decreased levels of CD18 (β2 integrins) suffer from life-threatening bacterial and fungal infections. CD11b, the α subunit of integrin CR3 (CD11b/CD18, αβ), is essential for mice to fight against systemic Candida albicans infections. Live elongating C.

Control of β-glucan exposure by the endo-1,3-glucanase Eng1 in Candida albicans modulates virulence.

Candida albicans is a major opportunistic pathogen of humans. It can grow as morphologically distinct yeast, pseudohyphae and hyphae, and the ability to switch reversibly among different forms is critical for its virulence. The relationship between morphogenesis and innate immune recognition is not quite clear.
