Abstract

Insights

Invariant natural killer T (iNKT) cells show potent anti-tumor activity against gastric cancer expressing CD1d. Chemotherapy can enhance this susceptibility, supporting iNKT cell therapy for gastric cancer.

Area of Science:

  • Immunology
  • Oncology
  • Cancer Therapy

Background:

  • Gastric cancer remains a significant global health challenge.
  • Understanding immune cell interactions is crucial for developing novel therapies.

Purpose of the Study:

  • To investigate the expression of CD1d in gastric cancer.
  • To assess the efficacy of invariant natural killer T (iNKT) cells against gastric cancer.

Main Methods:

  • Examined CD1d expression in gastric cancer cell lines and primary tumors.
  • Evaluated the in vitro and in vivo cytotoxic effects of iNKT cells on gastric cancer cells.

Main Results:

  • CD1d expression was confirmed in gastric cancer.
  • iNKT cells demonstrated significant anti-tumor activity against CD1d-positive gastric cancer.
  • Cisplatin treatment upregulated CD1d expression, increasing gastric cancer cell vulnerability to iNKT cells.

Conclusions:

  • iNKT cell-based therapy holds promise for gastric cancer treatment.
  • Combination therapy with chemotherapy may enhance treatment outcomes.
  • These findings support the clinical translation of iNKT cell therapy for gastric cancer.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Linear time-invariant Systems01:23

Linear time-invariant Systems

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...

What is Natural Selection?01:32

What is Natural Selection?

Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
Peristaltic Waves and Chyme Formation
Upon food entry, the stomach initiates...
