Mycobacterium tuberculosis penetrates the airway mucosa through M cells via the mycobacterial virulence factor EsxA and the host M cell surface receptor scavenger receptor B1.
The scavenger receptor MARCO and liver phagocytes are required for clearance of circulating alphavirus particles and thereby limit viremia and viral dissemination.
Host CD81 and Scavenger Receptor BI operate independently to mediate invasion of hepatocytes by different species of Plasmodium sporozoites, which use the parasite protein P36 as a key determinant of the entry route.
Structure specific nucleases that act in DNA replication, repair and recombination actively mold their DNA while transforming their own structure to achieve precise cleavage of their cognate DNA and avoid the deleterious cleavage of noncognate DNA.
Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.
A coordinated humoral immune response that includes recognition, effector and cytotoxic factors engages the cell-mediated immune response to defend a snail against infection by schistosome parasites.
The TRPV1, TRPV2 and TRPV3 channels are gated on the cytosolic side of the pore, whereas structural changes in the ion selectivity filter associated with activation don't control cation access.
Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.
Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.
