ABSTRACT

The field of two-dimensional (2D) nanomaterial-based cancer immunotherapy combines research from multiple subdisciplines of material science, nano-chemistry, in particular nano-biological interactions, immunology, and medicinal chemistry. Most importantly, the "biological identity" of nanomaterials governed by bio-molecular corona in terms of bimolecular types, relative abundance, and conformation at the nanomaterial surface is now believed to influence blood circulation time, bio-distribution, immune response, cellular uptake, and intracellular trafficking. A better understanding of nano-bio interactions can improve utilization of 2D nano-architectures for cancer immunotherapy and immunotheranostics, allowing them to be adapted or modified to treat other immune dysregulation syndromes including autoimmune diseases or inflammation, infection, tissue regeneration, and transplantation. The manuscript reviews the biological interactions and immunotherapeutic applications of 2D nanomaterials, including understanding their interactions with biological molecules of the immune system, summarizes and prospects the applications of 2D nanomaterials in cancer immunotherapy.

ABSTRACT

Objective:To explore the correlation between white matter lesions (WML) at different locations and cognitive function.Methods:The cognitive function of 68 patients with WML in Beijing Electric Power Hospital from January 2019 to May 2020 were assessed with Montreal Cognitive Assessment Scale (MoCA), and the extent of WML were assessed with age-related white matter changes rating scale(ARWMCRs). Correlation between the ARWMCRs scores of different locations and the scores of all locations and the scores of cognitive function, as well as the relationship between the ARWMCRs scores of different locations and each subitem of cognitive function were analyzed.Results:In 68 patients with WML, the degree of lesions in different parts from heavy to light was frontal area, parietooccipital area, basal ganglia area and temporal area, and no white matter lesions were found in infratentorial area. Except the basal ganglia region, the ARWMCRs scores in other regions and the total score were negatively correlated with MoCA score, among which, the ARWMCRs score in left frontal area, right frontal area, left parietal pillow and right parietal pillow region had the strongest correlation with MoCA score( rs=- 0.388, - 0.479, -0.418, -0.502, all P<0.01).In WML patients, the left frontal area was negatively correlated with language, abstraction and orientation ( rs=- 0.479, - 0.324, - 0.288, all P<0.01).The ARWMCRs score in right frontal area was negatively correlated with visual spatial and executive function, memory, language, abstraction, and orientation ( rs=- 0.324, -0.272, -0.459, -0.382, -0.352, all P<0.05). The ARWMCRs score in left parietal occipital region was negatively correlated with visual spatial and executive function and memory ( rs =-0.287、- 0.270, all P<0.05). The ARWMCRs score in right parietal occipital region was negatively correlated with memory, language, abstraction and orientation ( rs=-0.366, -0.289, -0.260, - 0.307, all P<0.05).The ARWMCRs score in left temporal region was negatively correlated with language, abstraction and orientation ( rs=- 0.248, -0.372, - 0.608, all P<0.05).The ARWMCRs score in right temporal region was negatively correlated with abstraction and orientation ( rs=- 0.525, -0.465, all P<0.01).The ARWMCRs score in right basal ganglia was negatively correlated with orientation and memory ( rs=- 0.455, - 0.275, all P<0.01), while The ARWMCRs score in left basal ganglia was not correlated with MoCA subitems. Conclusions:The frontal area and parietal occipital area are the most serious lesions in WML patients, and the lesions in these two areas also cause the widest range of cognitive impairment.
