Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

41.9K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Stereotype Content Model02:16

Stereotype Content Model

15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.0K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Microtubules in Cell Motility01:24

Microtubules in Cell Motility

4.6K
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

Cell Motility through Blebbing01:16

Cell Motility through Blebbing

2.5K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Actin Polymerization and Cell Motility01:13

Actin Polymerization and Cell Motility

6.5K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate....

Area of Science:

  • Quantitative Biology
  • Biophysics
  • Cellular Dynamics

Background:

  • Stereotyped behaviors are repeatable postures used to classify dynamics, easily identified in animals via anatomical landmarks.
  • Identifying stereotyped behaviors in single cells is challenging due to the lack of distinct landmarks and constraints on cell shape.

Purpose of the Study:

  • To develop a minimal model of cell behavior during migration using the maximum caliber variational method.
  • To predict cell behavior over minutes based on cell shape changes over seconds, without biochemical details.
  • To demonstrate the utility of maximum caliber descriptors in discriminating between healthy and aberrant cell migration.

Main Methods:

  • Application of the maximum caliber variational method to model cell migration.
  • Analysis of cell shape changes over short timescales (seconds) to predict behavior over longer timescales (minutes).
  • Utilizing drug treatment and genetic manipulation to validate the model's predictions.

Main Results:

  • The maximum caliber variational method successfully models cell behavior during migration.
  • Cell shape dynamics over seconds can predict cell behavior over minutes.
  • Maximum caliber descriptors effectively differentiate between healthy and aberrant cell migration patterns.

Conclusions:

  • The maximum caliber variational method provides a powerful tool for analyzing cell behavior without relying on biochemical pathways.
  • This approach has potential applications in automated disease screening, particularly for identifying behaviors linked to cancer metastasis.
  • The study highlights the significance of cell shape dynamics in understanding and predicting cell behavior.
