Introduction

The human immune system offers defence against harmful microorganisms and other external and internal hazards. In order to protect the body from outside substances, a number of anatomical physical barriers, including the skin, ciliated epithelial cells, the mucous blanket, and mucous membranes, are present. When foreign invaders get past these defences, the immune system responds quickly to protect the body against “non-self” invaders. The innate immune system and the adaptive immune system are the two main immune system components. An innate immune reaction is set off regardless of how frequently an infectious pathogen is met. The rapid response of innate immunity is dependent on receptors that recognise foreign substances, commonly referred to as Pathogen-Associated Molecular Patterns (PAMPs).

Description

Leukocyte defences against pathogens, cell-intrinsic defences against viral infections, and soluble mediators, including complimentary proteins, make up the innate immune system. These defences are non-specific, changeable, and instantaneous. T and B cells, on the other hand, are exclusive to the adaptive immune response. These cells produce antibodies that target and eliminate infections and aid in the recruitment of additional immune cells that assault the pathogenic factor upon identifying particular antigens provided by the invading bacterium. The effectiveness of a person’s immune system is significantly influenced by their dietary status. The body’s capacity to maintain innate immune responses may be compromised by under nutrition, which results from insufficient ingestion of micronutrients; however, the consequences of nutritional status vary depending on the disease.

Although an individual’s nutritional status may be used to predict the clinical course and prognosis of many illnesses, such as viral or bacterial diarrhoea, measles, pneumonia, tuberculosis, and others, nutritional status has little bearing on the course and consequences of other infectious diseases, such as viral encephalitis or tetanus, and only a slight influence on the onset of illnesses like HIV and influenza. Allergens, poisonous substances, and pathogenic and non-pathogenic microorganisms can interfere with the host body’s ability to maintain homeostasis. The host defence system employs a defensive mechanism known as the immune system to combat these intrusive elements. The identification of a toxin or pathogen by means of structural traits that set them out as invasive.

Toxin and pathogen selectivity is essential for the host immune system’s capacity to destroy the invading factor without causing damage to host tissues. There are two types of methods for determining if a structure is microbial, toxic, or allergic. The innate immune system initiates responses, and a wide range of cell types display the identification markers this system uses extensively. The immediate host reaction to the discovery of foreign particles is represented by the quick activation of the innate immune system in the presence of invading pathogens or poisons. The initial host defence against different pathogens is provided by the innate immune response, which is a nonspecific immune response present in all multicellular organisms.

This reaction is essential for maintaining cellular homeostasis, getting rid of a variety of infections, and helping the adaptive immune response get going. Physical and chemical barriers, as well as humoral and cell-mediated components, make up the innate immune system. Mast cells, macrophages or monocytes, the complement system, Natural Killer (NK) cells, basophils, and neutrophils are the primary effectors of innate immunity.

Many bioactive compounds, which have the potential to be turned into novel medications, have continual sources of leads in natural items. Chlorin e6 (Ce6) is a second-generation sensitizer with strong sonosensitivity that may be extracted from green plants or silkworm faeces. Studies have demonstrated that Ce6-mediated SDT can stop the growth of many cancerous cells, including human lung adenocarcinoma cells, breast cancer cells, and hepatoma cells (20). However, Ce6’s in vivo uses are limited by its low bioavailability, poor solubility, and propensity to agglomerate in the biologic media. The structural flexibility of several novel kinds of chlorin-based sensitizers has been extensively used for simple chemical modification.

Conclusion

For the treatment of early-stage lung cancer, talaporfin sodium [mono-l-aspartyl Ce6 (NPe6)] received commercial photosensitizer approval in Japan in 2003. The natural spirulina powders from Chenghai Lake in Yunnan Province, China, were successfully used in our lab in the past to make Chenghai chlorin, a chlorophyll derivative having the same Chemical Structure as Ce6 (CHC). Our first results showed that the extension system could precisely tune the photochemical properties, molecular lipophilicity, and even ROS generation capacity of CHC in favourable directions in PDT. Based on this, we hypothesised that the extension system may be able to enhance the sonochemical characteristics, SDT effect, as well as other molecular characteristics of CHC.
