Lectinas antibacterianas e antibiofilmes de plantas - uma revisão

Research, Society and Development, 2021
O número de bactérias multirresistentes que afetam a saúde pública tem aumentado e há recursos limitados de terapia para lidar com esses patógenos. A formação de biofilme por bactérias, torna a terapia ainda mais difícil. Nesse sentido, produtos naturais têm sido cada vez mais utilizados como fonte de novos antimicrobianos e as lectinas têm se ...

Uncovering the Binding Specificities of Lectins with Cells for Precision Colorectal Cancer Diagnosis Based on Multimodal Imaging

Advanced Science, Volume 5, Issue 6, June 2018., 2018
A polyacrylamide hydrogel–based lectin microarray is fabricated to screen new lectin biomarkers for colorectal cancer. Uelx Europaeus Agglutinin I (UEA‐I) is demonstrated to have high affinity and specificity with SW480 cells. Using silica‐coated NaGdF4:Yb3+, Er3+@NaGdF4 as a nanoprobe, the UEA‐I is successfully applied to differentiate SW480 cells and

Soluble Host Defense Lectins in Innate Immunity to Influenza Virus

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Host defenses against viral infections depend on a complex interplay of innate (nonspecific) and adaptive (specific) components. In the early stages of infection, innate mechanisms represent the main line of host defense, acting to limit the spread of virus in host tissues prior to the induction of the adaptive immune response.

LECTINA LIGADORA DA MANOSE: PROPRIEDADES, ISOLAMENTO E PURIFICAÇÃO

Visão Acadêmica, 2008
A lectina ligadora de manose (MBL) é uma proteína encontrada no soro humano, secretada pelo fígado e dependente de cálcio. A MBL é um importante elemento do sistema imune inato, que pode atuar por meio da ativação do sistema do complemento pela via das lectinas e por sua característica de opsonina, facilitando a fagocitose dos patógenos.
