Cell secretion therapies

Cell secretion therapies

Cells communicate by their secretions, impacting the behaviour of other cells. Cell secretion therapies use living cells to produce and secrete therapeutic substances that can aid in treating diseases. These include extracellular vesicles (EVs), cytokines, chemokines and hormones. Such therapies are at the forefront of regenerative medicine and immunotherapy.

Immune boot camps in cancer may explain the abscopal effect

Immune boot camps in cancer may explain the abscopal effect

A deadly arms race takes place between cancer cells and our immune system. A recent study published in Nature shows the importance of monocytes in the development of a healthy anti-cancer immune response, how cancer blocks monocyte activity and how this can be restored.

Tumour-mediated immune evasion

Tumour-mediated immune evasion

Tumours evade immune surveillance through mechanisms that impair immune responses, allowing the tumour to grow and spread without being eliminated by the immune system. Understanding the interplay between cancer and immune cells is allowing the development of new therapies.

Why is CAR-T therapy so expensive?

Why is CAR-T therapy so expensive?

Despite its promise and success in treating otherwise resistant blood cancers, CAR-T therapy comes with a hefty price tag, often exceeding hundreds of thousands of dollars per patient. Understanding why CAR-T therapy is so expensive requires a closer look at the complex processes and factors involved in its development and administration.

Simple, efficient reprogramming of immune cells

Simple, efficient reprogramming of immune cells

Immune cell reprogramming is widely used to enhance immune cell function for disease treatment. This approach is successful for some types of immune cell, such as T-cells, but reprogramming of monocytes, macrophages and other phagocytic cells has historically been difficult. At Cell Guidance Systems, we have simplified the engineering of monocytes and other mononuclear phagocytes by using PODS, sub-micron scale sustained-release protein crystals that durably alter the cell's proteome. This simple technique is opening new research avenues and has the potential to enable cost-effective autologous immune cell therapies to treat a range of diseases.
